I liked the ending of Strange 1. It's my favorite ending of all the MCU movies. Because Stephen didn't use his magic physically to defeat Dormammu. He used his intelligence. Actually Stephen defeating Dormammu and Hex Vision defeating White Vision were two of the most interesting "battles" I've seen in the MCU to be quite honest.
MoM. I'm looking forward to it. But not as much as I did before the Loki series. I was curious to see Strange as a "horror" character. I mean Raimi is pretty good at this stuff, but Derrickson seemed really passionate about his vision for Stephen. I don't wanna have loads of exposition about the rules and mechanics of time travel/multiverses in this movie. But I think we might get that. I do think Strange 2 will be really visually entertaining though.
