I gave it an 8. I thought it was a definately a good, solid trailer. I'm still not entirely sold on Spacey yet, and Shia is still annoying (but he's supposed to be i guess), but I got to see more of Routh as Supes which is good since I've seen almost nothign of him so far. It's interesting, because the way this trailer came off for me is that this is much more a character study type of film with some action moments kind of like Hulk.
Now I've heard that there both are a lot of action sequences and that there aren't either. IF there aren't that many, than this was a great trailer for it IMO. One of the Hulk's biggest problems was that everyone just expected it to be a huge action movie and they were dissapointed with a character study. To, me, this trailer made me think that this movie will be a character study with some actiona along the way, which is definately not a bad thing.
