I think the opposite as well. I think Rob took it way over the top with the self loathing, the only time I thought he did well was in the 2-3 scenes in which he was happy. I also don't think it was all his fault. The way they scripted the scene where he jumps around and freaks out was pretty terrible...

Oh and -- I just thought his voice was really, really weird. Especially when he first talks to Bella...I dunno it was just off to me

I thought Kristen was pretty spot on with how I pictured Bella --> Kind of awkward/uncertain/weird.
