Two giants of the boxing world (literally and figuratively), Vitali and Wladimir Klitschko knocked out fans of the sweet science (thankfully, not literally) by becoming the first brothers to hold world titles simultaneously. This doc on the hulking Ukrainian champs details their respective ups and downs: Vitali's career was cut short with a shoulder injury before his 2008 rebound; Wladimir suffered setbacks after a 2004 Lamon Brewster bout before becoming one of the greatest boxers currently punching. Even with incredible fight footage, however, all we have here is a standard if formless ESPN hagiography, complete with a cheesy cop-show score and little sense of who these guys are outside of the ring.
