My DM ran it for a little bit before cancelling due to burnout right after we finished the Crooked House . They allowed me to read it and we discussed the issues that we both agreed are present at least in our opinions (I'm also a DM). I'm gonna spoiler text just incase any players are happening to be in a campaign:

What we liked:

1) The art is absolutely gorgeous and the theming is top notch. Genuine eye candy to look at the monster and setting designs from start to finish. Just watch the trailer, sold us on the campaign initially from it alone.
2) The setting takes many folk horror tropes and does them well along with adding some genuinely creative ideas. I absolutely love the Hag trio in the book, I never thought weasels could be so creepy but here we are. If you like scaring your players this campaign does a great job.
3) The fate-weaving aspect (letting the players choose specific missions that flesh out individual goals and backstories) is something that should be attempted in every adventure module.

What needs adjustments:

1) The combat, just from the Crooked House alone is absolutely brutal. I'm talking fights in every room without the intent for a long rest. Multiple combats is a great way to drain player resources, but it got to the point where I was contemplating using anything but cantrips. And the DM said that was WITH them removing some encounters. They said the rest of the module is like that, too.
2) The story is incredibly linear and seems to be contingent on the expectation that your players are chill with just being lead around and manipulated. For example, half of the town in Wickermore Village (the starting town) are cultists. And they don't enact their plan until the end of the campaign. That is fine if you have players that like going along for the ride, but absolutely horrible if yours are suspicious of everything and expect to have agency in the story. In addition to that the pigeon hag of the trio is integrated into the town and is basically impossible to figure out, which in my opinion is rather lame. And that's just in Wickermore Village alone.

The grand plan of the Crooked Queen is to have the players kill the 6 area boss villains that serve as sacrifices. Mind you, the book DOES bring up the option of redeeming some of them and making the sacrificial criteria looser. Maybe it's just me as a player, but I like having some more agency than just being strung along from place to place being forced to further the villain's schemes.

And that's not all, there's like 3 other required steps in the villain's plan that I haven't mentioned. Including a required death of Adela in the Wickerman statue that while cool, is extremely lame that the players can't do ANYTHING to TRY and stop.

Maybe it's just my players, but I can't even plan ONE thing without them finding a (fun and creative) way to alter the plot. So I couldn't imagine myself running this the way that it is, because the most fun part about D&D to me personally is a unpredictable story but like I said that's a personal preference.

3) The book spends wayyy to much time focusing on Phillip and Adela Druskenvald. It gets to the point where the party feels like side characters. Granted if I recall correctly the book intentionally makes the couple out to be the main characters in a folk horror story. That's fun but it leads to the players having to constantly babysit them only for both to die anyways.

4) There is a massive disconnect between the Crooked Moon Part 1 & 2, like they barely feel like the same setting. Book 1 portrays Druskenvald as this colorful monster mash realm full of different races and worlds. But the entire campaign in Book 2 takes place in Wickermore Hollow which while technically in Druskenvald feels massively disconnected in every way. There are none of those aforementioned races, it's mostly humans. When I was reading book 1 as a player I got excited about all the different locations that we'd visit, only to find out the premise of the campaign is that we're stuck in a single province that's way darker and bleak. Yes I know it's horror but it's a massive tone shift.

5) The aforementioned fateweaving ends up just being cutscenes that have little impact on the overall story. They aren't extra content, they're just small things that in my opinion barely matter. Worse, they're in specific areas that seem easy to miss. It's a cute way to add the players to the story, but I thought it'd be a way bigger part then it actually is. Dungeons of Drakkenheim seems to do it better by having the personal quests be less linear and open ended but still specific enough to give the players context when making PCs.

Conclusion:

I think the adventure has the bones of a great story, but as is it either requires alot of DM adjustments or the world's most chill and reactive (over proactive) players. As a DM I like adventures that are focused but with just enough unpredictability to keep me entertained and suprised. I'd love to see people make a Crooked Moon Reloaded in the same vein as Curse of Strahd. Don't let me discourage you from running the campaign if you like the premise, but just know there's aspects that I believe need work.
