Several factors compel you to ponder over your decision whether or not to watch Knock Out...
There's talk that Knock Out is a blatant copy of Phone Booth. If you've watched the original, why watch its clone?
You rush to a nearby cineplex only if the film excites you and in this case, the buzz is missing.
Sanjay Dutt - the lead actor - hasn't been a part of a worthy film, post Munnabhai. That automatically robs the sheen from the film.
You can't turn a blind eye to the fact that Knock Out borrows from Phone Booth. Even otherwise, a man held hostage in a telephone booth by a sniper automatically compels you to think that Phone Booth is the prime source of inspiration, but what follows after a point bears no resemblance to that film. In fact, Knock Out also bears an uncanny resemblance to A Wednesday although the two films are as diverse as chalk and cheese in terms of how the storyline progresses.
