This is a fun one.
Some of the downsides - It's a huge file. 45 pages for a 2-hour adventure.
The handouts are nice, but it really complicates the logistics of running this.

Everybody loves Blooddrinker! I want to run this again and again just to give more characters that story reward.

My party was hooked immediately on coming to the aid of a Flumpf. Then they murderhoboed their way through the rest of this dungeon crawl.

This one worked well only because some of the players had played DDEX1-1. Otherwise, they'd have had a hard time caring for the NPCs. Riding the roller-sleds underground was fun, but a battle where they're all prone (and thus at disadvantage while the enemy has advantage) is potentially TPKing. Beware.

My players really enjoyed this, expecially the finale.
My tip would be to enhance the random effects of the pool. Make every touch of the pool have an effect. My players started doing this during the big fight at the end and it really amped up the fun.

The encounter with the coven was a stand-out memory from this one. Some players were quick to cash in on the hags too-good-to-be-true offers and that made for some fun as the others were really skeptical.
The battle at the end with the BBEG was great. Some of the characters were a little miffed they didn't get to finish off the BBEG.

Really long adventure, and I likely won't ever run it again because of that. You could edit out the travel to the pyramid to save an hour or two. The maze with the shifting walls was really fun.

I folded up post-it notes on my battle map to show the shifting walls and the players had a blast.

I would have enjoyed it more if it had been divided into several smaller adventures, like they did with DDAL05-06 Beneath the Fetid Chelimber
and DDAL05-07 Chelimber’s Descent.

This was a blast! Such a huge increase in power in the enemies and the PCs in their first tier 2 adventure.
My group had both Lord's Alliance and Harpers factions represented, so it was a bit of a challenge to present them both secret missions in a logical manner. If they go to Stojanow Gate first, they won't have the Harper secret mission yet. If they go to the docks, there's no compelling reason to go the Cracked Crown and meet with Glevith to get the Harper secret mission. Be flexible. Let Glevith join them at the gate. Have a random encounter where Elsinade delivers a note about the secret mission.
The death of [spoiler - notable NPC] was a punch in the gut for my group. Be sure not to reveal this until it's too late to use revivify, because it's a plot point later on.
Even after adjustments, the encounters seem quite strong for a party of level 5 characters. DMs take caution.

I ran this adventure when I was too new as a DM and I didn't handle the fight at the end very well. I had the third party show up too early, before the players had a chance to meet or talk to Sahnd Krulek. Kings Pyre was a bit too open ended for me as a newbie DM.
Some advice for running this says to cut the whole jailbreak scene. I kept it in and I'm glad I did. It was a lot of fun to add a charging minotaur to the mix. My group always runs long, but this one was especially long, about 7.5 hours, split over three sessions.

This was a lot of fun. The players liked Pipyap, probably mostly because he sounded like a mob gangster from Brooklyn. I had lots of opportunity to play up Jeny Greenteeth as a badass way more powerful than the party can handle, even though though they could have defeated her if they wanted. The real kicker was that the players were left in a huge moral quandry. Rescue the two men from the village from getting eaten or salvage the alliance between Jeny and Phlan?

This one was fun. The players were a bit frightened at the prospect of a Dragon in the area. Halfway through the big battle at the end, the group didn't seem to understand why they were fighting the lizardfolk, and a truce was struck. Bogclaw was defeated and allowed to live.
Giant toads are suprisingly tough if they manage to swallow a character or two. Almost had a TPK going there.

This one begins quite similarly to 1-5 The Courting of Fire. I suggest running 1-7 Drums in the Marsh between 1-5 and 1-6 to change the pace a little. (It would also provide some good foreshadowing of the fight at the end.)

Good RP and investigation opportunities. We had fun with the three theft victims. The fight with the fake welcomers would make more sense if your group includes a Zhentarim faction member. My group didn't have one, and then accused Cassra of the crime. Fortunately they didn't outright murder her before getting to the truth.

DM advice and spoilers: The quarreling with Master Opanrael about an appointment seems unnecessary and petty. Keep it if you have the time, but mostly it just wastes time and makes the players feel powerless. Maybe that's the point, that the heroes can slay dragons but not get an appointment with the scribe master?

Dragon fight! A battle with a dragon almost never happens in D&D anymore because it's so cliche. The lair actions can make or break the fight. Please do your players a service and play the dragon smart. A fight with a dragon should never be a cakewalk.

This one went well. At the start it's quite similar to 1-6 The Scroll Thief, so maybe space them out a bit by doing 1-7 Drums in the Marsh before this one. (That would also make for good foreshadwing of The Scroll Thief)

DM Tips and possible spoilers: The rules of engagement for Spernik meant he stood around and helplessly pleaded with the adventurers to leave while they solved the key trap puzzle. Once they realized he had the two missing parts, the fight took place, and it was a fairly easy encounter for a strong party. I'm not sure how I could have handled that better.

It has some shortcomings and poor editing, but it's still one of my favorites from Season 1 tier 1. Big dungeon crawl, a fun NPC with Cassyt, and it scales well for big or small parties. The map is huge, beware.

Spoiler alert and DM advice:
A few things to watch out for. There's a big "shortcut" from the second room right to the end. This will cut out almost all of the action if the players take this route. I advise cutting it out.

Similarly, the "Necropolis" is a cool idea, but if your players go searching in there, they'll waste a lot of time and resources for little to no gain. Cut this out too.

Related, who is keeping the brasiers lit in room 5? Hard to think it's the Kelemvorites, negotiating that ledge around the bone pit. If you need to do this under 4 hours, cut this dead-end hallway.

The description of room 14 indicates there are trap(s) in room 12, but there aren't any there.

It's hard to present the timeline to the players. Another reviewer has offered good guidance on that. I recommend using it. If you get that info into the players hands, they should figure out to go to the right place. The encounter with the madman Yip is a bit of a waste, he doesn't have any real information to offer.
I had a problem with my players metagaming; that is, asking the NPCs for specific details about the invaders they had encountered: are they ghosts? Undead? Did you need magic or silver weapons to hit them? Etc. Beware of this. In their defense, it does seem like they're being sent into battle against a dracolich, which would oblitterate a level 2-3 party.

The town is frusrating to the players. They're there to help them, but the vilagers don't seem to want their help, and it's nearly impossible to convince any to join the characters. Elsenade is a fun NPC, though. She makes an appearance in a later adventure.
The final battle on the ship is fun.
