Forbes' Scott Mendelson: The Film Doesn't Work

"in a desire to highlight his youth and inexperience, the film turns Peter Parker into a dangerously incompetent would-be superhero. At its core, Spider-Man: Homecoming is 133 minutes of Peter Parker failing the "first do no harm" rule of super heroics."
"There is (unless I missed it) no reference to Peter's actual origin and the film stumbles by essentially making Parker's desire to be Spider-Man less about his guilt or even his willingness to help and more about impressing Tony Stark."
"we spend an entire movie watching this wet-behind-the-ears wallcrawler screw up repeatedly (while depending almost entirely on Tony's super-suit and its various toys) only with the promise that he'll be the competent and inspiring superhero in the next installment."
"maybe once it moves past treating Spider-Man as the world's worst superhero for the sake of cheap laughs while retrofitting his arc so that he's doing what he does for the approval of a cool adult, we'll be on solid footing."
