First off: yes, the movie is raunchy, but would you expect anything different from anything with the title "The Hangover"? No? I didn't think so. So don't act all surprised about it.
Review: The movie is definitely funny, don't get me wrong, but of course we all know that the "funny" in this movie isn't exactly best to be seen by a younger audience. You should be worried if you allow any child who is NOT A HIGHSCHOOLER to watch this movie. Okay, some of you parents are probably shaking your heads, but hear me out - us highschoolers know a *lot* more than you give us credit for (haha, some of you are thinking to yourselves "They think they know everything."), and if you're afraid of "exposing us" to all of the raunchy stuff in the Hangover 2, let me give you a tip - We've seen it before. Nothing's better exposure to all of this stuff than highschool. Parents, you just have to trust that your highschoolers aren't going to grow up being like the characters in this ridiculously funny movie. If you *can't*, then, well, I feel sorry for you.
Overall - funny movie. Not for little kids. Highschoolers should be allowed to watch it. Parents need to relax because we just want to see the movie as much as they do.
