Of all the films screening at the Tribeca Film Festival this year, it was a documentary called This Is Not a Robbery that pulled me in the most at first with a description that teased the real-life story of an 87-year-old bank robber. Who wouldn't want to know more about a really old guy who robbed banks? And the film itself definitely entertains for awhile, as it takes us through the life of one J.L. "Red" Rountree -- from his early days chasing skirts on a farm to his last moments on earth inside the prison system. The problems with this film don't necessarily have to do with the story (which is a fascinating one), but more with length. As with another documentary I've seen at Tribeca (Gotta Dance), after about a half hour it starts losing its steam. Here's an old guy who liked to rob banks. Here's a little bit about him and why he liked to rob banks. Now, here's another hour full of interviews (with people who can't believe he robbed banks at 87-years-old) and pretty graphics and ... do we really need all this fluff? This Is Not a Robbery would've made for an excellent, award-winning short film. As is, it's just okay. Fun for the first half hour, then a bit too repetitive from there on out.
