This was one of my favorite modules i have run, it was a blast. I pulled out the Chult nouns and dropped it into our homebrew west marches campain. Tense, terrifying at times, and frantic. My players grew to love the NPC's before they were ripped from them.

My players strategized, thought how to defeat the monster, all while desperately looking for a place to rest and regroup.

That being said, it depends a lot on the players and a DM to set the tone. I can see this falling flat or feeling too oppressive or unfair to players that aren't in the right mood.

And watch predator!! There are some beats and character aspects from the movie that really make this module shine.

Man i wanted to like this one, the bones are there. i like the fact that there are few combats and lots of puzzles and traps. i like that it is a 2 parter. good reward for a magic caster. however half the puzzles were badly written and confusing (especially the ritual chambers), the book layout in the library was confusing, what books can you take? what are the effects? the resistances were bad, i can translate resist 5, but some of the elements dont map to 5e elements. the story reward only helps wizards. this definitely seems written in an afternoon without checking the rule books and never really edited.
