So no woman in her underwear this time?
No, but I doubt that'd hurt kids anyway.

I can only think of two scenes that might be a little disturbing.
The crew member who is left behind in a room is the big one. The other is when Krall is talking to Uhura and Sulu and then shows them why he's still alive.
In general I'd say the movie is too visually exhausting for a five-year-old but what do I know.
