Spider-Man 3
I get that some alien goo from outer space, apropos of nothing, lands mere feet away from the protagonist. I get it.
I get that an escaped convict, the man who killed the protagonist’s uncle, stumbles into an open-air particle-accelerator thing, and that he thus gets the ability to commune with and manipulate sand. I totally buy it. I get that a bump on the head is guaranteed to give another antagonist amnesia just when the protagonist most needs it to happen. I get that in a city of eight million people, the protagonist and another antagonist just happen to be in the same church bell-tower at the same time, so that alien goo can drip from one to the other. I get all that.
What I don’t get is the career of Mary Jane Watson.
