Mission Impossible 4-6. I love 7 and 8 as well but because they haven’t been out as long I haven’t rewatched them as much. Personally I’m a big fan of action movies, I really enjoyed watching James Bond, and Jason Bourne, but I’ve always come back to Mission Impossible (or at least the ones after three) because it was really nice to get that same level of excitement but still have a clean movie.
