I love these kind of comments. This is something I'd expect a 12 year old to say.
Some time before it's release, some people were wingeing that Prometheus might be a PG13 and not R rated. Those people seemed more bothered about the possibility if it being a PG13, than they were about it actually being a good film. It was confirmed that is was R rated, and those people breathed a sigh of relief. Yet, so many people complained about the film being poor and disappointing. Nobody said it was great just because they gave it an R rating instead of a PG13 rating. Did not having an R rating suddenly make the film great?
You can have as much death and violence as you like, a poor film is a poor film. Still, some people are easily pleased I guess.
