How i myself think Spider-Man 2017 movie could be:
An intro in the beggining, showcassing Peter's story up until the Civil War, he moving with his uncles, the bite, wrestler times, the Uncle Death, vigilantism, a war between two titans, Peter's present The movie would actually start with the news,it would be very news based on how people react to a newbie Spidey, this time the news talking about Spidey's recent battle with a supervillain (Doc Ock, Shocker, White Rabbit, etc) and how it affected the area, at this time Peter is very reckless in battles, people don't die but there is still damage done.
Peter is in high school, he isn't really that much of a nerd but he is an outcast due to his personality, some see him as this shy kid, not very social, but in his group of friends he is this very animate guy, very relatable and quite nice.
The movie's villains would be either Mysterio (surprise, surprise) or the Spot.
Mysterio:Quentin Beck in here is still a special effects professional, mostly using practical effects and due to that he is quite famous in the film community, he is currently working on a documentary about The Avengers (from the Battle of New York to the fall of Sokovia), but during the filming, Spidey fought against a villain causing damage, injuring most of the crew. The reason he is fired is due to the people on top being a*******, but Beck doesn't see that, he thinks he was fired because of Spider-Man, at his most deep Beck is quite unsure and tries to succeed and being respected, this driving him into taking the fish bowl, the robes and the green suit.
The Spot: In here, Johnathan Ohnn worked for Kingpin, he was his tech guy, and since Fisk was arrested, John has been working secretly on a teleporting technology, thinking in using it to make himself rich, he himself just wants a big score and to get money, to be powerful, and when he becomes the Spot, he thinks to make this big score one way or another. But his classic looser personality is still there, he is still the Spot. His role in the movie would be a bit smaller, heck a constant joke could be him trying to tell Spidey his origin constantly, every time getting interupted.
The movie would mostly be about Peter as Spider-Man and as Peter Parker, he being a teen and Spider-Man, but not he and love issues, but he as a student mostly and his relation with his recently widowed aunt.
