I'd pick Community and Due South, but I hate the last season/two seasons (it was shown as one season, but all the fans of it seem to insist it's two) so I can never recommend it (I felt Paul Gross had no idea what made that show so great when he took the reins of it after it was rebooted, and reboots of shows really rarely do what made them great in the first place). So you might want to take my advice with a grain of salt. Still, man, I loved those first two years of Due South. I love Leverage, too, and Slings and Arrows is really unlike anything else you'll watch on TV. Fringe was fantastic but they changed the focus from the female character to the male, and it kinda went off the rails--still, Olivia will always be a favorite character.
