Ant Man and the Wasp isn't special as a movie, much less so as a Marvel movie. While it does have some passable visual gags, it is riddled with plotholes and spends the first few minutes dishing out exposition that you could easily pick up if you've seen the first Ant Man and Captain America: Civil War (why would you watch a sequel before the original, anyways). The product placements in this movie are particularly blatant, which is saying something for a Marvel movie.

Still, like I said, a few of the visual gags are passable, and the fight choreography is enjoyable, but as a movie that doesn't exactly need to exist in the first place, it's better to be avoided to save some money. You're not missing much.
