While there are certainly episodes from Batman: The Animated Series that are better than this feature-length film, Batman: Mask of the Phantasm is arguably the second best Batman movie ever made, right after The Dark Knight. The plot is a breathe of fresh air from the DC character's live-action projects: There's a new, enigmatic criminal terrorizing Gotham City, and he (or she?) looks dangerously close to the Caped Crusader, which leads people to believe that the bat has gone bad.
Foolishly, Warner Bros. tossed Mask of the Phantasm into theaters on Christmas Day 1993 with barely any pre-release hype. And since nobody even knew it was coming out, the millions of die-hard Bruce Wayne fans who'd otherwise flock to it didn't catch up with Mask of the Phantasm until it hit the home video market.
