Honestly Electro was not needed in this film and his removal could have fixed a lot of the overstuffed feeling it was getting. You get into his arc and character at the beginning of the movie while he's still Max, and his initial Electro appearance in Times Square, giving you a feeling he'll have an big character arc you'll see progress throughout the movie, but then after that he just becomes a shallow villain character, overshadowed by Harry's transition into Goblin.
Also could have done without the whole Peter's parent's subplot, it honestly didn't further the movie and wouldn't change much if that whole plot was missing.
I'm pretty happy to see they had the balls to go with this death of Gwen Stacy as well and in the same manner with the web snapping her neck from the impact.
Or did she actually hit the ground in the movie? I forgot in all the excitement.
Her death was VERY well done though.
I'm also pretty ticked that all the Rhino we got to see was pretty much what was fully shown in the trailers. They need to tone it down on their trailer exposure next time around.
