You remind me of a friend of mine.
He refused to watch the Lotr movies, because, in his opinion, anything so popular could not be any good.
-he says that Lotr movies, because of their popularity, must be populistic and generic, and could not have any edge, or artistic value. And he still keeps saying the same! And he still refuses to see the films!
Same with you and Twilight. You think the movies must suck because they are so popular with common folk.
-but has it occurred to you that movies became popular simply because they really are good?
