This adventure runs ok in the alloted time. The first part is just exposition that explains all the stuff that has happened earlier in the campaign. It could be role played out but you'll probably do it as just a big data dump. That said, it's an interesting story and explains a lot of stuff from earler adventures. The stuff in the village should probably be done as Theatre of the Mind because it's mostly about impressing the players with all the obsessions. The players will probably just want to restrain the dangerous villagers and rescue the others. The fight with the trees was ok but nothing special. The final boss fight was great. There was a cool villain speach then a really hard and interesting fight. Omou had great spells as well as legendary and lair actions. But he wasn't too dificult to run because there were't too many choices. The players definitely felt like they had been in a fight.
