Iron Man (2008)
I watched this to see if the kids could watch it (answer: not yet). I didn't expect to like it, but I really did.
(I know I could fast-forward through any offensive parts in this and other movies. But I'm pretty sure the fast-forwarding would only happen the first time, while I was watching it with them. After that, the kids would just remember that they'd seen a movie, not which part to skip. But they can wait a little while. They might think it'll kill them, but it won't.)
