The film "Air" benefits from a cast with strong chemistry and consistently good performances, notably featuring Matt Damon. Alex Convery’s script is a highlight, delivering some of the best writing seen in sports biopics lately; it manages to mix humor and dramatic elements well, even if it doesn't attempt anything radically different within its genre, sticking to expected conventions. The fast-paced conversations make each scene very watchable, so the nearly two-hour length doesn’t feel long. Ben Affleck demonstrates his skill as both a director and performer. It proves surprisingly captivating, even for those who aren’t fans of basketball. This is a genuinely pleasant and skillfully made story about how a single shoe had a significant impact. Rating: B+
