Jon Watts’s Spider-Man: Homecoming (B+) marks the superhero’s seventh on-screen adventure (as played by Tom Holland, he most recently had a minor but memorable role in Captain America: Civil War) and his first standalone Marvel movie, with small bits by a quintet of actors popularized in other universe franchise series. Thankfully this third reboot of the series eschews the origin story, spider bites and uncle tragedy and simply lets Peter Parker be a regular high school kid with an extraordinary extracurricular life. Tom Holland is superb as the awkward arachnolescent, and the film’s best sequences show him fumble through the stickiness of growing up. Following other roles in the bird and bat family, Michael Keaton is strong as villain Vulture, a salvager turned arms trafficker who assembles Avengers scraps into fancy new weapons. Watts is inventive with the teen scenes and largely successful on the action front (disaster sequences at Washington Monument, aboard a Staten Island Ferry and at Coney Island are believable). The stakes seemed a bit smaller than the usual Marvel epic, but the characters reveal themselves nicely. Robert Downey, Jr. is fun as mentor/impresario Tony Stark, and Jacob Batalon is a delight as sidekick Ned. Effective storytelling and upbeat, compelling characters continue the Marvel winning streak.
