Finally got around to seeing this over the weekend and it did not disappoint. Hands down the best Spiderman ever and a great addition to the overall Marvel cinematic universe. Holland's quirky Spiderman was full of energy and optimism - a refreshing change from darker and sadder incarnations. I like how they skipped over the origin for a change (didn't need to be redone yet again), and giving him a buddy to share the secret with was another refreshing change. I initially thought Vulture would be a lame villain, but he was great too - especially with the ties back to the Avengers and alien tech. I love how they're using that explain and include a plethora of C-level baddies. Shocker was obvious, but some great nods to other potential characters like Scorpion and Prowler, and even a possible tie to a Miles Morales Spidey down the road. The level of Stark inclusion was just right - I was worried he would be too involved, but I thought it worked out really well. Some nice plot turns that I did not see coming and that ending was awesome. They even brought back Pepper for a cameo! Even the very last extra scene after the credits was a gas. Looking forward to seeing this one again and more Spidey goodness in future movies.
My only complaint is still Zendaya's Mary Jane. Not a fan of her acting in general, but casting her as a nerdy recluse instead of a popular hottie is a total mystery to me. She didn't serve any real purpose throughout the movie - maybe they left something more meaningful on the cutting room floor. I think it would have been better to just leave her out of the movie. Similar thoughts about the redesign of Flash Thompson, though he had more reason to be there as an ongoing antagonist/rival. Still, pretty rare to find an overconfident mathlete ladies man who DJs at parties.

Forgivable choices overall.
One question for those that have seen it - (spoiler) - Did we actually "see" Stark and Pepper get engaged off scene? I couldn't tell if that was a meaningful off camera plot point or just a simple ruse for the reporters that we won't hear about again.
