Personally, I had a blast whether I was a player or a DM.
Quite a bit of RP at the beginning, and a really big fight at the end. Quite honestly, you could easily TPK in the boss fight. I love to reward inspiration if players get into the RP, and my group went whole hog. Every one of my players had at least 1 inspiration, which they all used in the boss fight (mainly for saves). The final fight can be scaled according to your group, as all DDEX modules can be, but forcing PC vs. PC combat can get really weird for a group if they are not experienced.
