I shouldn't dock it a whole star for not having surround or captioning, but I'm gonna.. Otherwise, this was even better than season 1. The FX improved enough to be notable. The story ideas are interesting. It's a neat idea, and I enjoyed it when it was new. It's still fun, but in retrospect, I can see some limitations in the direction. Might be hard to go back to if you didn't watch this when it was actually on air.
Specific to the version I acquired: Kind of annoyed that this (Canadian release) version had no subtitles. Audio channel is kind of quiet relative to other DVDs/Blu Rays I have also. Neither of these are deal-breakers, but just be aware.
