I actually loved that show.
Numb3rs wasn't too bad - not "great" television, but I watched most of it once and was fine with it. It was one of the first TV series put up on Netflix Instant that I saw which was how I found out about it. Pretty much the same as every procedural out there.
I started watching Fringe a few weeks ago (thanks to Amazon Prime Instant Video), just got to the end of season 2... holy crap. I'm sad I missed this while it was running but being able to watch an episode or two every night does let me pick up a lot of things that I would have missed if I watched one episode per week.
