Even though I enjoyed the first one as a comedy movie itself (and not a hero movie, more like an "introduction" movie into becoming some sort of hero), it was "ok" for me the fact that they inserted a very generic, uninteresting, forgettable villain in it (by now we always expect this kind of villain in MCU introduction movies).

Well, this time they expanded the team into Ant-man + Wasp, which was nice. But that was the only main change (besides the after-credit scene).

They still managed to create the same structure of the previous movie, instead of a "hero movie"...again a comedy movie... instead of a well developed villain, again the same uninteresting and forgettable villain.

Personally I think I lost money watching it since it was again more of the same, maybe I have should waited until it was on Netflix or something.
