I was also at the premier and my opinion is quiet a bit different than Zurbs, I honestly thought it was mediocre and did not maintain the level of the first two films. I won't go into spoilers but just in case, STOP READING NOW if you don't want to know anything.
There were too many villains so they were each given very little screen time and no chance to really deeply develop.
They change Spidey's origin slightly and IMO unnecessarily. Gwen Stacey served very little purpose and honestly could have been anyone else with that name and it wouldn't have changed anything. The way they handled Peter turning evil was laughable and embarrasing...seriously.
The last fight was too long.
Up to about half way through, I thought this is going to be really good then it was like the movie went off the rails and they tried to do WAY too much and wound up hurting the movie.
Think Superman 3 or 4 I forget which where Superman is split into two and, while not that bad, it makes a pretty good comparison.
My review 7 out of 10.
Finally, the after party was a lot of fun, I spoke with James Franco and they are trying to get the original cast to do 3 more but he doesn't think Tobey will do anymore. I believe Cliff Robertson is in poor health, he looked like he was having trouble walking. The food and booze was good and ultimately, that is all that matters
I am interested to hear what other think once they see the movie.
