Guardians of the Galaxy Vol. 3 (out May 4) is a (just) good enough entry to close out the story of these music-loving superheroes. The villain is dull (have they run out of ideas?) and the action is a bit too hectic but, this is still entertaining because of its comedy and the chemistry between its leads. The tone is light, the zingers and plentiful, and there’s a splash of genuine emotion at just the right moments. Grade: B.
