The tone was all over the place, even for a Raimi movie.
Venom was clearly an afterthought, as was Gwen.
Sandman killed Uncle Ben, more or less negating the whole power and responsibility thing.
Climax was Mary Jane being kidnapped again.
Butler conveniently explaining to Harry about his dad being a fucking nutbar and making Harry forgive Pete.
Sandman just fucked off and the other villains died.
The romance was weak despite 2 damn movies of build up.
Sandman's motivation being muh daughter but we see her once.
The fights were less memorable compared to Doc Ock's elaborate brawls or Green Goblin's brutal ass beating.
