What Happens: Having partially bonded with the naughty symbiote Venom, Peter Parker becomes a bit of a prick, growing a fringe and, in one particular sequence, using his spidey powers to do a jazz-dance at Mary Jane’s nightclub. 

Why It's Stupid: The Venom stuff was one plot strand too far anyway for Raimi’s overwrought threequel, but if you’re going to do it, do it properly.

That means not showing Peter Parker’s moral degradation through the medium of goddam bodypopping.
