“Seven Cemeteries” (** out of four) was a thinly conceived action melodrama about a recent parolee (Danny Trejo) who enlists the help of a Mexican witch (Maria Cannals-Barrera) to resurrect his posse so they can enact revenge on a vicious drug lord (Sal Lopez) and a corrupt sheriff (Ronnie Clark). Mildly amusing and relatively watchable but a little of this goes a long way and it wears out after a while. Trejo’s rock-solid presence and effortless charisma give film a strong charge as usual.
