Babylon 5: The Complete Series is on sale for over 50% off at Amazon for Prime Big Deal Days. The Blu-ray box set released last year to commemorate the franchise's 30th anniversary. At launch, Babylon 5: The Complete Series cost $135, but you can add the set to your personal collection for only $66.49. This deal is expected to expire when Big Deal Days ends tonight, October 9, at 11:59 PM PT.

This Blu-ray collection features all 110 episodes of the series, as well as the 1993 feature-length pilot, Babylon 5: The Gathering. If you're looking to complete the collection, you can also pick up last year's CG-animated feature film, Babylon 5: The Road Home, for $18 at Amazon.

What makes this version of Babylon 5 notable compared to other releases over the years is that it's the first time the show has ever been remastered in high definition, giving fans a sharper look at J. Michael Straczynski's groundbreaking show. Released during the golden age of '90s sci-fi, Babylon 5's use of CG technology to craft its space station and interstellar dogfights put Star Trek to shame, as its rival still relied heavily on practical effects and models.
