(PG-13) ★★★☆☆

Teenagers acquire super powers (and videotape them) in this sci-fi romp, an excellent and fresh effort with impressive effects. Our three newly endowed teens are naturally going to handle their powers differently. Nerdy Andrew (Dane DeHaan) will bully his bullies and try to save his dying mom. Cerebral Matt (Alex Russell) will test out “free will.” And popular Steve (Michael B. Jordan) will enhance his popularity. With great young actors, a sharp script and first-rate effects, this is a winner.
