Man I fucking love it!
I started watching TV shows on DVD a couple of months ago and I almost cannot tolerate watching them on TV anymore. This all started when my wife decided to get "caught up" on Grey's Anatomy. I didnt care much for the show, but I saw how she was able to completely catch up on a couple of seasons in a week, so I have started doing it.
I have very little time in my life for shows, but this is nice, because I don't have the pressure to set the DVR or whatever for sundays at 8 or whatever. I am hooked, and I am now working my way through six feet under.
