Continuity mistake: During the battle with Green Goblin, when Gwen Stacy is falling through the clock tower, there are dozens of gears and other pieces of various sizes falling with her. However, when she lands, only a few small gears and pieces land alongside her - all the other debris that were falling have seemingly vanished. (02:01:20)
Suggested correction: That part of the scene is SO dark that it's really hard to tell; they do show some gears and pieces land after she does and there are some gears and pieces next to her when he walks to her. I wouldn't say there's none, but I'd say it does seem a disproportionately low amount considering how many giant gears were falling.
Given that even you admit in your correction that the number of gears seems disproportionately low (which it is - we only see a few small pieces landing when there were dozens and dozens of pieces in different sizes falling), I think amending the wording through a word-change is a better option than trying to correct the mistake itself. Because there is still a mistake here. Going to go ahead and do that after I post this response. (Might take a few days to change, though).
