I just saw Crank .. an incredibly stupid movie with Jason Statham performing violence, sex in public and other kinds of general nastiness. It was fast paced action with with a touch of comedy right from the start.
Chelios (Statham) is a hitman who's gotten himself poisoned by some concoction that blocks adrenaline receptors. The result? He'll die .. unless he keeps the adrenaline pumping. While he's trying to get revenge on his would-be killer, he has to make sure his adrenaline stays high, for example by random acts of violence, public sex, drinking excessive amounts of red bull or even forcing a doctor at gunpoint to give him a hit with the defibrillators ..
Actually, it was pretty darn enjoyable! Watch it if you can enjoy a simple action flick that simply aims to entertain.
