Hmmm, odd about the lower star reviews, especially lacking any sort of feedback.
This was one of my favorite 4e adventures. I mean, DECK OF MANY THINGS, interacting throughout the entire adventure, and it isn't completely broken?! Confession, when I was 11 I made my own Deck of Many Things out of playing cards after encountering it in AD&D.
In all seriousness, large variety of encounters, some pure combat, some social, traps, heck, even mass combat on a more wargame scale too!
There are good 5e conversion kits out there, and I have sucessfully run this twice for groups (once in 4e, once converted to 5e), and even used the theme/world/flair for another group.
