Here's the thing guys. Sony took two shots at Petey Parker. One with Toby McGuire and one with Andrew Garfield. They tried the awkward, schmucky Spidey and the too cool for school Spidey. Neither was very effective. Plus they burned through a bunch of villains and killed off the Green Goblin in the first movie. They made quite a few tactical mistakes.
Miles makes sense and I'm not convinced they use him in the current storylines past CW. They could use him to run through the gambit of villains that made ASM 1-20 such great reads in the first place. I'm talking Scorpion, Kraven, Mysterious, Vulture; etc.
Miles could work, if for no other reason than Sony did Peter Parker no favors. I would not write off the UF 4 for around $20.
