Highly recommend The Raid:Redemption playing now on Encore I think. Police strike team leads all-out assault on inner city high rise under the control of a ruthless drug lord. The mayhem escalates from floor to floor, as the strike team battles the various bloodthirsty tenants on their way up, using guns, knives, fists, and explosives to unleash an unreal level of mayhem.
The climactic battle between three of the key characters at the end is one of the most brutal, extended fight sequences ever filmed this side of They Live. Seriously, it's that good.
