BraVO. I don't think there's anything disturbing or grim about the first half, I thought it was funnier than the second one, which was, umm, visit a lousy amusement park and go in a ghost ride, that's the "horror" you get out of it. It's funny. It's funny. When I was a kid, I saw in theatre and I wasn't scared I just thought it was cool.
About the first half - it's not real violence - it's making fun of violence. Look at the news report, it reminds me of one in our local TV, there was a report about some drowned guys and the reporter is talking about this accident and in the background we see two guys (rescuers) in a boat poking the corpse with some stick, while it's floating in the river, I wish I had it recorded.
