The title talks about a slaughterhouse, so I reckon no one should be surprised that this actually is quite violent. Even if the school that is named that way was not intending to go that way. They only wanted to establish meanness verbally and psychological ... if you know what I mean. You probably do and even if you don't you'll get into it right quickly.
But while the movie is kind of adult in one place, it is almost childish in other places. So tonally I can see that quite a few people may have issues with that. It's also cool to see Nick Frost and Simon Pegg in a movie together. Even if they don't share much screen time. Margot Robbie on the other hand is phoning it in ... Just kidding (or pun intended). So if you can dig the various moods and the fact this is adult yet childish ... you are on a good way to enjoy watching the movie (which is quite predictable)
