I'm going to say right away that I really enjoyed the first Ant-Man. I'm not really a fan of the Marvel Cinematic Universe, I've only seen about half of the movies and I've only really liked about half of that, but Ant-Man is up there with my favourites. It was the most fun movie I had seen in a while! That being said, I did not enjoy Ant-Man and The Wasp very much. There were way too many characters with way too much going on for what should've been a pretty simple story, it was too long, everything was all grey, and the action scenes I thought paled in comparison to the first movie. My favourite part of the first movie was all the creative things they did with all the growing and the shrinking in the action sequences. They didn't do a lot of that in the sequel. I don't really know what happened. The same people who made the first movie also made this. What made the first movie so good but the sequel so underwhelming? Was it what was left over from the original Edgar Wright version? Was it my expectations being too high? Are they just running out of steam with these movies? I can't put my finger on it. There were some things that I enjoyed, like the comedy, the performances, and the post-credits scenes, but that's about it. I found this movie very dull and quite disappointing. Check it out if you're a die-hard Marvel fan, skip it otherwise and just watch the post-credits scenes online somewhere. That's all you really need as far as context for the other movies goes.
