You could tell from the trailer that Ant-Man and the Wasp wasn’t intended to be a particularly serious movie. Unfortunately, it wasn’t a particularly funny one, either.
Dr. Hank Pym (Michael Douglas) and Hope Van Dyne/Wasp (Evangeline Lilly) briefly open a tunnel into the quantum realm. Scott Lang/Ant-Man (Paul Rudd) magically receives a message from Janet Van Dyne/original Wasp (Michelle Pfeiffer) that’s she’s still alive after all these years in the quantum realm. Then it’s a relentless series of size jokes and feds acting like Keystone Cops. The whole thing is very one-dimensional and mostly falls flat. Oh, there’s also an antagonist named Ghost (Hannah John-Kamen) who meanders in and out and mostly exists to give Ant-Man and Wasp someone to fight with. Walton Goggins shows up and plays pretty much the same guy he always plays.
I must give some credit to Michael Peña as Luis. He’s not given much to work with, but he manages to be pretty funny, nevertheless. He’s clearly the best part of any scene he’s in. Abby Ryder Fortson also does nice work as Ant-Man’s daughter, Cassie.
