Reasons why this great movie has a only 5 out of 10 stars

I'm portuguese so i'm sorry for any mistake I make

This movie is incredible, but it isn't for most people.
The main reasons are:
( There could and should be some exceptions )

1 - Most people that love Twilight and came for Robert Pattinson are to dumb to understand this.
2 - Most people that hate Twilight don't give Robert Pattinson credit as an actor, and don't give credit to none of the movies he's in, and even before seeing his movies think they are awful.
3 - Most people that don't read good books will not understand this.
4 - Most people don't understand Cronenberg, and because they don't understand his movies they automatically think they are bad.
5 - Most people think Cronenberg only makes movies with gore, sex and violence and find his movies offensive.
6 - Most people have been influenced by the Transformers movies, and if a movie is a little slower and more character driven they don't understand it.

I loved the movie and these were the reasons that I tough that made more sense for me. Please post more and argue with me.
