realism can it be to real

After having some time to consider last weeks lecture, i keep considering even though we all want films,no matter what genre, to be as real as possible is this crossing a line into the real world. their are more horror movies which are dealing with real events, rape, gang violence, sadistic torture, we watch films to escape reality is this direction of film making bring these aspects, to realistically to the viewer. Don't get me wrong i love horror and i like it to be as realistic as possible but are these latest trends starting to take the imagination and creativity out of the genre.
