Now, if I were to say anything negative about this scene (and trust me, I think it's absolutely awesome, so these details aren't very important to me) it is:
1.) Spider-sense...
I agree with all the other posters the mentioned that Pete's spidey-sense should've gone off before Harry picked him up off the moped.
I understand that this would sorta get in the way of the entire action sequence, but they could've easily worked around it, for instance have Peter jump out of the way the first time (with spidey-sense effect and everything), then have the moped out of control and moving/flying towards a kid (or something) while Harry makes another pass. Now Pete would have to ignore Harry's second attack in order to save whomever it may be from the moped crashing into them. A split second after the save is complete, Pete's picked up by Harry.
Spider-sense problem solved.
2.) At the point where Harry chucks away a bunch of pumpkin bomb blades (or whatever you wanna call'em) he makes a funny sound.
Yeah, that's right. I said these weren't very important details.
3.) The moment before Harry is clotheslined is too long. That is, considering the time he has to react, he should've been able to dodge that piece of webbing. Harry's surprised reaction to the webbing should've been either made shorter or cut out.
That is it.
