Review from the comment
I'm a big fan of the Marvel Cinematic Universe. In my opinion, the last average or below movie they made was Avengers: Age of Ultron and I still enjoyed it enough. That said, the first Ant-Man movie was to me not of the caliber that Marvel had been rolling on. It was decent enough, had a good balance of laughs vs action, but the lack of a good villain bogged it down a little. Ant-Man and the Wasp runs along the same lines although it has an even better balance of humor vs action pushing it past its predecessor. There are better villains here too. Check it out for a fun watch.
