For me STID was a 9. Absolutely loved it, and a couple of parts almost had me in tears! I saw it Friday and immediately wanted to see it again, so today I saw it in 3D IMAX. Not a fan of 3D, but I've got to hand it to them it looked brilliant. I'm surprised the B.O. wasn't better than it was, because imo It's a much better movie than IM3. Hopefully the great word of mouth this film is getting will assure that it has long legs. I'd certainly see it for a third time.
MOS's OW B.O. I think depends on how good WB's advertising push is in the last few weeks leading up to the release, and if we keep getting compelling new imagery with each subsequent spot. If the film is great and it resonates with audiences outside of the North American market, then 1 billion should be doable. If however, WB's hasn't got the message out to enough of the GA that this movie has zero to do with SR, then it might not do as good as we all hope.
I think one of their strongest weapons is actually Henry. They need a couple of more spots, like the Lois interrogation scene where he and Amy are flirting and making goo goo eyes at each other. In that scene, they are so playful, and Henry simply oozes charm and charisma. Amy isn't too shabby to look at either!
