The first few weeks of the new year usually see few big releases, but there are some discs coming out this week that are worth seeking out. Be sure to check out these titles: Machete [DVD review, 2nd DVD review] - Robert Rodriguez managed to turn a two-minute gag trailer into a thoroughly funny B-movie diversion; The Last Exorcism [DVD review]- a horror flick that is innovative, supremely creepy and intelligent; and Dinner for Schmucks [Blu-ray review]- a funny picture that pays careful attention to the rituals of dumb guy cinema. Other reviews of note include: Dirty Tricks [DVD review], The Guilty [DVD review], and El Mariachi / Desperado [Blu-ray review].  Visit the DVD Talk Review Database for all the latest reviews including an entire section devoted to reviews of DVDs out this week.
