During reading the OP's first post, I was expecting something of a pornographic raping nature, but I found the RP not of the sort. The RP was fine in my oppinion.
My line is: anything that borders into pornographic detail = unsuitable. Blood and gore = acceptable.
There are worse horror films out there, Im sure many 12 year olds have sat down at watched.
Good to see this thread being mature and civilised.
