But seriously the first four seasons were AWESOME. After season 4, the show runner changed and the last four seasons were not as good. I HATED the last season. But once you get sucked into the first four, you do feel like you need to finish it.
ETA: Have you guys watched Breaking Bad? That's on Netflix and is too awesome for words. Plus your H would probably like it too.
Nice, but I totally agree with others about skipping at the very least the last season. Such a HUGE disappointment. Unlike Breaking Bad which just got progressively more amazing as it went on.
