Yes, I think on current showings it'll come in third behind the Avengers and DKR. Although saying that the Avengers, as much as I'm really looking forward to it, is either going to end up being an horrendous mess or great fun and I honestly couldn't say for sure which it'll be yet... though the last trailer made me lean towards the latter. I'm not particularly a big fan of the Avengers, or the characters (I always felt Cap was dumb, Thor really dumb, and the Hulk usually quite dull), but I've enjoyed the films so far by and large - Cap is worth a look by the way, I don't understand how some people really derided it, it's basically a boys own adventure, pure pulp fiction.
I'm a Spidey fan, I just don't see this reboot blowing anyones socks off. I think it'll just be a decent action film. There's nothing so far that really looks outright bad (though I'd argue they've made a really, really big error with the Lizard design and some of the CG looks ropey at this stage). I suspect audiences might be tired of Spidey and will feel a reboot is a little cynical right now.
The Dark Knight Rises I'm all over
