Of course it begins with jokes about Fox and getting cancelled. The new "action" titles are a fun gimmick. Then the plot kicks in, involving naked aliens with a time travel device who send Bender back through history stealing historical artifacts. The universe, however, can correct the time paradox of doubles, which causes problems for anyone who goes back to a time when they were already alive.

That totally works for the movie because it's like a series of shorts that only include all the funniest stuff. There are threads interweaving everything into an epic, like the aliens whose overall plot continues to affect things, and characters who weave in and out of multiple stories.

The complex time travel story sets up easter eggs from the show's run, as well as things it will pay off by the end of this feature. At the same time, there are dick jokes and cartoon butts (Yes, Amy and Leela included). There are joyfully silly puns that feel like the creators saying, "Yeah, we know math but we also screw around."
