Personally, I think Spidey 3 had some VERY cool fighting scenes, some of the best I've seen in a movie of this type, but the plot was all over the place. And, although I felt weird at the time in the theater, I now recall that dance scene fondly as one of those WTF moments in movies. There must be a gif of dancing movie spidey somewhere out there, I'm sure.
As for this one, I just hope that Denis Leary turns out to be the Green Goblin at the end of the movie.
Peter's a regular boy genius though, having made that quality spidey suit, the web shooters and all... And the lizard is pretty cool too.
