It's a bit of a slow week for new home video releases, but there are still some discs you might want to take note of including: Dirk Gently [review] - Douglas Adams' holistic detective arrives on the small screen thanks to the BBC and the results are some cracking good tales; John Dies at the End [review] - director Don Coscarelli (Bubba Ho-Tep) releases his first film in a decade and it has flashes of exuberance and wit, and its manic comic momentum carries it a long way; and Knuckleball! [review] - a documentary on a pitch used in baseball may sound odd, but the history is fascinating, the protagonists are likable, and there's some genuine emotion in its concluding sections. Be sure to check out our DVD Talk Review Database for all the latest reviews including an entire section devoted to reviews of DVDs out this week.
