Wow,where to start? Let's see. They were very lazy with both the introduction of the symbiote and the creation of the Sandman. I mean,the symbiote just falls out of the sky during a meteor shower and hitches a ride on the back of Peter's scooter. Then,it just hangs out in Peter's pad for like,half the movie doing........nothing. I mean,was it hanging out in Peter's underwear drawer or what? Then,Sandman. The cops chase him into a field where scientists are doing who the fuck knows what with a bin of sand. There are a bunch of lasers over the sand pit that what's his face falls into. Then it cut's to a group of scientists talking about some "temporal anomaly" or some shit occuring in the pit. Then they turn the lasers on with old dude in the pit. Blend for two minutes

OOF! Instant Sandman!
I like Topher Grace alot and was looking forward to him being in this movie. But his character was just annoying and stupid. The whole being humiliated and praying to God to kill Peter Parker? I thought it was going to be some major occurance that Parker does to Brock while under the influence of the symbiote. But no. Peter exposes that Brock used Photoshop to fake a pic of Spidey showing his "true colors". What?!
Mary Jane,once again,was reduced to screaming victim. Shit,even Parker smacked her ass around this time. She reminds me of the crain game,where you think after about fifty attempts,you're finally going to get the piece of shit toy you're trying to grab,but no. Just at the last second,it falls right back where it started.
Harry Osborne. It was as if they decided to add him back in at the last second and didn't want to do any rewrites. "Let's just have him fuck Spiderman up,give him amnesia,have him regain his memory,somehow talk Mary Jane into breaking up with Parker(again,WHAT?!)and redeem himself at the end when the butler decides to tell him the truth about his father. Ummmm,can anyone say a little slow on the info? The butler could have told him that in the last movie and saved everyone a ton of grief.
There was just too much shit crammed into this movie. You can tell that they crammed two different ideas into one movie. It wasn't nearly Batman Forever bad,but damn it was dangerously skirting being that way. I think I've vented enough here. I'm going to go watch Spiderman 2 and purge this one from my memory.
