Questions about Spider-Man 3

Rating: 6/10 (5 May 2007)

Here are a few questions, in no particular order, that came to me during and after seeing the film: *Be warned some questions are a bit spoilerish*
1) Why didn't the Broadway play producers not know that Mary Jane's voice wouldn't carry past the first row? Isn't that something you find out during the audition process?
2) Did the story really need to have Gwen Stacy and Eddie Brock connected?
3) Is the half-torn Spidey mask now an official look for him?
4) What was they symbiote doing in Peter's apartment in the time between it arriving and it leaping on him? Watching soap operas? 5) Why did Eddie Brock get sharp teeth when the symbiote joined with him?
6) Does Spider-Man have some kind of one person per rescue quota? After he saved Gwen I couldn't help but wonder about the poor crane operator. Was the crane still out of control? Were they able to cut the power?
7) Why would a villain with a "heart of gold" like Sandman join up with a clearly evil creature like Venom?
8) Was the New York subway system designed by the same people who created the mine tunnels in Indiana Jones and the Temple of Doom?
9) Why would Mary Jane go along with the whole "Dump Peter or I'll kill him" plan that evil Harry proposes? Did she forget that Peter is Spider-Man and that he can pretty much take care of himself in a fight? Or did she just use that as an easy out for what she really wanted?
10) And where was the scene where Evil Peter would fight Good Peter in a junkyard?
