re: Spider-Man 4: May 6th, 2011
I don't remember Brock being mentioned in #1, but I do remember Peter out job hunting because "Dr. Connors fired me." Of course, Dr. Connors' role turned out to be a bit different in the subsequent films as well, so I'd just chalk such references up to being there soley for fans to catch. The actual plan for those characters were clearly thought up later.
That being said, if Raimi can keep his cast together for another one, I say go for it. And I thought #3 was a dud, too...but now that whole mass of plot material is out of the way (along with Venom), and Raimi can cut loose and do whatever he wants. I think he knows this, too, and if given one more shot, he's got another film on the level of the second one in him.
So cook up a good script this time and go for it.
