[quote name='UjnHunter']I'm torn... I love me some Firefly, I own the DVD of the series, as well as both DVD versions of the Movie & HDDVD of the movie... But I'm not sure how much of an improvement the Blu-Ray is to the series... and for $40... argh! :\[/QUOTE]
Picture wise, it's very substantial, except for the shots that were intentionally filmed with that 70s look still have tons of noise. The sound is 5.1 now, but isn't as big leap as the video.
It's worth the price to upgrade...especially if you will watch the series more than once. However Amazon's price isn't all that great. In winter there were a couple of etailers that had this from $30-$40.
