Here's what I didn't like, pretty much from start to end.
*I didn't like how long Spider-man kept playing with Aleksei through the truck window instead of trying to stop him. A little is fine, but after a while it seemed irresponsible.
*I didn't like how Spider-man fails two times to punch through a windshield.
*I didn't like Norman's crazy finger nails.
*I didn't like how Max Dillon was so pathetic before he gets his powers and suddenly hates Spider-man for no reason. From then on he's a different person. Right around the time he starts spouting lines like 'It's my Birthday, time to light my candles."
*I didn't like the metal lyrics you could hear when Electro was on screen. It was annoying, didn't fit.
*I didn't like how Spider-man stops two people from touching an electrified bar in slow motion during the Time Square fight. He was too far away to reach them in time. It looked fake. Plus, he just saved one guy from the car, that would have been enough. He's good but he's not magic.
*I didn't like that Dr Kafka was a man. Why not just make him Dr StilWel or something?
*At the start of the power plant fight, I didn't like how Electro repelled a stream of water by shooting electricity at it.
*In the same fight, I didn't like how Electro shouts electricity on Spider-man's face. Looked fake, and weird.
*I didn't like how Green Goblin grabs the retracting blade thing in his left hand, and then somehow stabs at Spider-man with it in his right hand.
That's about all.
