I might be in the minority here, and I hate to be mean-girling another woman, but I’m tired of this air of fake gravitas she puts forth in every single picture she poses for. She always looks like she’s either no fun to have around or thinks too highly of herself. Maybe she’s just shy, but her demeanour just screams “unlikeable” to me. :/
I don't think she comes across as unlikable at all, but I see where you're coming from - she does look uncomfortable, or sometimes even annoyed, when she's on the red carpet. I think she just doesn't feel completely at ease with it, which is understandable, it must be bizarre to suddenly be faced with a wall of cameras flashing in front of you. She seemed more relaxed about it before the garnered so much attention for An Education - I don't recall her looking so stiff before the whole Oscar furore.
