In any case, the important stuff: who looked good. Most people looked quite lovely last night (Diane Kruger, Sandra Bullock), but in my opinion only Zoe Saldana had a "wow, that dress is crazy beautiful" moment. If you didn't see her in it, try to watch a quick video, as pictures do nothing for how the bodice of that dress looks under the lights.
There were only a couple of not-so-great dresses as well: Charlize Theron looked pretty, but had one of those "it looks like someone is grabbing her boobs" dresses on. And SJP, well, I don't what happened there.
