This may sound silly...but honestly. Any MCU film. They have become my all time favorite film franchise. Surpassing Star Wars, Star Trek, Lord of the Rings, James Bond, or any other classic. 20 films without one “bad” film in the bunch. That itself, to me, has to be one of the greatest achievements in film history. No one has ever even come close to 20 enjoyable films in a row. And they keep getting better.
I own them, but I would go back to the theater to see any one of them.
