“Chokehold” (*1/2 out of four) was a murky underworld melodrama about a woman (Melissa Croden) who seeks revenge on the Russian mob for the brutal death of her father (Casper Van Dien) and she becomes an underground fighter in MMA to find those responsible, avenge his death, and become a star in her own right. Haphazard mix of martial-arts and organized crime elements has little to recommend it, even for MMA fans. Croden is blank in the lead role and makes you long for the eloquent acting abilities of Gina Carrano. Van Dien and Lochlyn Munro are wasted in token supporting roles.
