He should've quit, yes, but let us remember, even with the eyeliner and dancing, he DID film the more better scenes of Eddie and the symbiote that I believe would've redeemed the film. Sure, I hated the whole idea of how the symbiote changed Peter into some hipster, but I would've brushed that off if we had gotten the scenes that would've brought meat to it, such as Eddie with the symbiote meeting Flint and his daughter at the park; the scene of Flint meeting up with that doctor about curing Penny. Scenes such as those which would've made more sense to the entire film and respected arcs.
