I don't know, but this may be superstitious, but it seems like when someone makes a comparison to God, God likes to screw it over, just for spite.
For example,
"God himself cannot sink the Titanic" and Boom!
Comparing Raimi to God, I don't know, God may just make it a sucky movie to spite people like that.
Meanwhile... I like Batman Returns Better than Batman Begins. But I really do like Begins, pretty good.
And, as old a horse as this is to beat, I will anyway. I don't think Raimi has made a completely flawless set of Spidey movies. He's made good choices, but bad ones too. Sink Spidey's intelligence and humor just to punch up his angst-ridden youthful angsty-ness? Doc Ock is basically a "good" person who is mindcontrolled by his evil tentacles?
But, these decisions haven't sunk the movies, they've stayed afloat regardless. But if this Uncle Ben Flint Marko thing is true, I don't know. That might be what sinks it for me. It just seems so... "Joker Killed Batman's Parents."
