I completely agree with this point. The irony of Sandman's role in this movie was that Raimi took a beloved classic goon with little characterization in the comics, tried to legitimize him with a ton of backstory and motivation, and then ending up having to cut the hell out of it so that it didn't even resonate anyway. On principle I was ready to indulge him, but in practice there wasn't any justification for Sandman to be in the movie crowding things up. I still loved the movie, but it was this in particular that made me question, for the first time, if future Spidey movies wouldn't benefit from a new (probably next generation) production team.
