No big spoilers, just one *ahem* small detail.
The funniest thing about this was when my dad was talking to me about it. He asked what the deal with the "giant ant he rode."
I stared at him a moment and said, "dad, you know there's a reason for them calling him Antman, right?"
He looked confused.
"...It's because he can shrink to the size of an ant...that's what he was riding."
So I guess that detail doesn't translate well for non-comic book readers.
