I saw this again yesterday, and my feelings are still very mixed, the good parts were even better 2nd time around, but the bad parts were also worse i'm afraid, so my rating doesnt go up or down, its still between a 7.5-8/10 for me.
When this movie soars though, it really soars, after being disappointed with them 1st time around, I really liked Spidey's fights with Electro 2nd time around (though they still should have been longer) and DeHaan, Field, Stone and DeHaan were all still great in their roles, despite getting some poor material.
On the other hand, after loving the opening 1st time around, I didnt like it this time around, Spidey puts just as many people in danger as pre-Rhino does, at one point taking the stirring wheel and hitting other cars with the truck, didnt like that, and didnt like him taking so long dealing with the threat, and having to stop the bus and save Max were both his own doing as well. Just didnt seem like Spiderman to me. When people are in danger, Spiderman's 1st and only priority is getting people to safety, which he didnt do in this opening, but he later did against Electro.
Loved the score a lot more 2nd time around, but was disappointed with some of the CGI, in 3D it all looked damn good, but in 2D more than a few looked very cartoony. When you consider the CGI in the 1st movie was pretty much flawless, this was a disappointment.
Overall though these movies need an improvement, and fast. For me Webb is a big problem, as both movies from him have seemed very unfocused, and dropping story points in the middle of the production of both movies couldnt have helped. And yeah the parents thing? Could have and should been resolved in the 1st movie, it just wasnt needed here.
