Using organic web-shooters was a horrible mistake, and I know why they did it. James Cameron wrote a disgusting, heathen scriptment for Spider-Man that featured organic mutations instead of scientific prowess. Thankfully, they didn't let Cameron direct the movie, but they had his stuff on file. They intended to use mechanical web-shooters, but the props were giving them trouble. They figured "hey, we have Cameron's monstrous idea, and it would save on props, time, and it looks smoother." Lazy bastards. That's all it is, laziness. They had a way out, and they took it. I condemned them to the deepest pits of hell for that decision, but when the movie out, I didn't mind it as much as I thought I would. Cameron's scriptment put a lot of emphasis on the "man-spider" metamorpohisis, and Sam Raimi's movie did not. They didn't swell on it or make it overtly disgusting, so it went down easy and didn't make me vomit. Next to the bigger mistakes they made in the movie, their glossed-over webshooter bastardization looked like nothing.
The Green Goblin suit has a different problem for me. Instead of being badly conceived, but better in appearance on screen, it's the opposite. I like the idea of the suit and glider being a military contract for Osborn. However, their is no excuse for that costume. Why does it look like an alien costume, you ask? Because Sam Raimi is a punk in many ways, and one of those ways is recycling actors (including his brother), material, and designs. He directed "M.A.N.T.I.S." Don't remember it? Don't feel bad. Point is, it's a similar costume, designed very insect-like. I would much, much rather see the Goblin in scaly, rubbery, non-segmented armor with a purple tunic over it than the Power Ranger special we got treated to in 2002. An insane villain like the Goblin needs a face that has expression. They should have used prosthetics.
Don't go dissing the man-purse. It's classic, it's true to source material, it's functional, and it goes with his stocking cap, purple jogging suit and pointy shoes. Gobby's got his own fashion goin' on.
