You are right. I do not agree. I found myself enjoying the strained dynamic between the vampire and the human (because that is exactly the way it is supposed to be I believe). And they definitely have chemistry. I got it, along with more than several other movie patrons, I might add. Anyway I doubt many here will get it. People see exactly what they want to see, especially when it comes to everything about these movies.
And for your information I am not exactly a Twihard, I am just not blinded by the hate bandwagon and look at it as objectively as I can. Worst Screenplay I can completely agree with but definitely not Worst on-screen Couple! I have seen so much worse in many movies this year.
