That is interesting! I had never heard that before.
Spider-man 3 was not good. It did, however, have massive potential to be good. The idea of a movie where Peter's rage drives him to a deeper and darker place until he finally learns to make peace with it is compelling. Unfortunately, by introducing the symbiote Peter's emotional arc is stunted. Nothing he does is his fault and the consequences of his actions are never explored. This movie could have been great. Regardless of whose idea Venom was (and I have always heard that Avi Arad insisted on Venom) the choice to put the symbiote and Venom in the movie was a bad one. And, ultimately, a choice the franchise has never recovered from.
Peters emotional arc was stunned by the completely wack dance scene that came out of nowhere
