It's just a shame that this show was axed before it got a conclusion (even a TV movie to wrap things up. but then again The Pretender was 1 TV movie short of a conclusion). Though I might be wrong but it was a casualty of the a writers strike rather than ratings.
You could just buy it on DVD no? And if you already have it on DVD why are you bothering with the bluray version? I've had a Bluray player for going on a year now and I still haven't felt the need to upgrade any of my pre-existing movies to the new format. That goes for tv shows as well.
