Like I said, a monster from space is a much more satisfying explanation.
And I completely understand that 1 & 2 had some problems (3 goes without saying), I just don't like people who are excited about 4 (is that what we're going to call this, or B1?) trashing the original trilogy. 3 had real problem thanks to Sony's involvement, but 1 is good and 2 is a great superhero movie (93% on rotten tomatoes).
I'm getting really sick of this mis-remembering of the Raimi Spiderman films. Peter was portrayed as extremely smart in the previous films as well.
As much as I understand it is cannon, there are a lot of reality problems with the Peter making the shooters (they are so incredibly powerful he should really give the design to the police).
