I agree about Natalie Portman. She didn't wreck it, but it was a poor performance. She's a research scientist, but then gushes like a school girl whenever Thor is near.
What, scientists aren't allowed to have libidos?
Natalie Portman as the love interest in Thor is WAY worse than Kat Dennings, in my opinion. I just got ZERO chemistry between her and Chris Hemsworth. Like, really, this is the woman you consider giving up your godly powers for? THIS woman? Portman's a talented actress, but she's just....wrong for that part.
Whether as written, directed or performed, her characterization was inconsistent--when Kat Dennings was ogling half-naked Thor, Natalie rolls her eyes....then is all hot for him later?! She falls for him AFTER he puts on a shirt? :lol
