It is nice to see Spider-Man 3 get a bit reevaluated now that so many years have passed. A friend of mine crapped on the movie quite a bit after it came out, though he's a contrarian with everything, and I don't think he's ever got an opinion of his own. That being said, his tune changed once he saw TASM. and as the years go on, and comic book films have somewhat lost their originality (it's true, whether people want to admit it), S-M3 feels like a product of bygone era and I think it's only gotten better and more entertaining with age. I'll always be a fan of S-M3 despite some of it's flaws. Yes there's a lot going on, but we have to applaud Raimi for being able to juggle it as well as he did with all the studios pressure on his back to inject things into his story. Also, the dance stuff? It doesn't bother me. The whole point of that was to show how much of a fool Peter looks nice due to the symbiote.
I'd also argue Raimi made Eddie Brock a more interesting character too.
