The hardest part of watching Marvel's "Ant-Man" is thinking about the "Ant-Man" movie you're not watching. Once you finally make peace with that fact, however, the film we ended up actually getting is actually still pretty good in its own right, delivering a fun and brisk-minded micro-sized jaunt into the Marvel Cinematic Universe without the burden of the MCU - or its own tortured production history - weighing on its tiny pest-sized shoulders.
