Saw an advance screening this weekend. Ask me anything.
I was lucky enough to catch a super advance screening! It was mentioned that they are still working on it, so some of the scenes might be added/removed.
I thought it was better than KFP2. The animation was fantastic, especially the Spirit Realm (you'll know when you see it). Story was simple, kinda was hoping to see some more development. Runtime was quite low, around 1 hr 20 mins or so. It was entertaining though. I would give it 7.5/10
