Good commentary and I liked it a lot, especially Teague flipping out from time to time 
Spiderman 3, to me, is just a mess of missed opportunity. It's like they had all this good source material, lessons on what not to do as well as good villains to work with-what could possibly go wrong?
Yeah, we all know the answer to that question.
In my opinion, Spidey 3 is just too much al packed in to one movie with no clear direction or focus. I honestly do not think I would have made it through the movie without having watched or read an other Spiderman material.
First of all, Venom, as many have said, is completely underused. Venom is probably the most iconic of the Spiderman villains and instead of getting his own movie, he is relegated to 3rd fiddle against Sandman and a poorly designed Green Goblin redux. Venom should have been the capstone villian, or a build up for a (dare I say it around Teague) 4th movie where Venom is the villian and is tearing around Manhattan in a brand new alien suit. The fact that Spiderman is powerless against him provides a little more character motivation.
Secondly, Peter's transformation as being close to bad is not even close to frightening or shows any risk. In all honesty, I think the animated show presented the the Venom arc much better. Instead, we get the unintentionally funny scenes of him "going to far" or something like that.
Lastly, if you are going to introduce conflicting love interest, shouldn't there be some chemistry between the characters?
All and all, I think DiF did a great job reviewing this movie. I could say more, but I think I will leave that to the commentators
