This was an unexpectedly good movie, one of the best I've seen in a while. It was interesting, funny, and it had action in it as well. There were few iffy moments, (a girl flashes Finn, and you see it), but otherwise, it's not too bad. The language isn't that bad, and the violence is pretty mild for a pg-13. The biggest issue is probably the sex content. None is actually shown, but it is talked about, and there is innuendo. Also, if you're uncomfortable about it, there are two gay characters, but there is nothing innappropriate about them, and they are comic characters anyway. It shouldn't be an issue, but I thought I'd mention it just in case.
Overall, it's a fun movie, and I recomend it to anyone 14+.
