Just hear me out for those of you that if not seen the show it's an adaptation of the ultimate spider-man comic book and this show has been a huge success already passing 2 seasons and a third is in the process of being made but through all this the story would make a great live action film and here's why.
Introduction of relatively unknown characters
On the show Peter Parker(Spider-Man) is recruited by Nick Fury to join a team of young budding heroes like him. The likes of whom are Power-Man(Luke Cage) a bad ass with super-human strength and bullet proof skin who is relatively unknown but is getting a Netflix show. Then there's White Tiger(Ava Ayala) who is a martial artist in who has electric claws and flexibility probably only spider-man can match. There's Iron-Fist(Danny Rand) who is a pacifist but packs a wicked punch using his chi as a weapon and finally Nova(Sam Alexander) the human rocket enough said. With the sinister six set to appear in Amazing Spider-Man 3 these five could help even the odds for spider-man
Possible rivals for Spider-Man
With CW's Arrow is introducing a character similar to DC's Blue Beetle on the show to act as a rival to Green Arrow. It's gotten fans pretty excited why not do the same thing with Amazing Spider-Man introduce these characters as rivals to Andrew Garfield's Spider-Man at first then make them team up to face the common threat of the sinister six that one movie could completely redefine the Spider-Man franchise.
The opportunity for Marvel and Sony to share the cash horde
On Ultimate Spider-Man nearly every Marvel character has appeared to battle or team up with Spider-Man from switching bodies with Wolverine to retrieving the Iron Spider suit from Iron Man. Spider-Man's adventures start when he was recruited by SHIELD with Fury's promise of turning him into Ultimate Spider-Man
A movie like this would make box office gold for both Sony and Marvel
Introduction of new and beloved characters
Like I said before Spider-Man has adventures with the likes of Deadpool,The Fantastic Four and even Blade this give the opportunity to introduce Deadpool to the cinematic universe through Spider-Man as in the show he was formerly recruited by Nick Fury but left shortly before Spider-Man joined the team so the rivalry thing could come up again with a younger version of Deadpool.
