Veronica Mars was a show far better than it's network. Airing on UPN and its affiliates, it wasn't available to the entire nation when it first aired. UPN was known for its comedies with all African American casts, appealing to a niche market now dominated by Tyler Perry on TBS. Given this, I know not enough people watched the show when it was on air, myself included. I caught the seasons on DVD, after the show was already canceled.
All three seasons are available on Netflix Watch Instant, but with each season consisting of 22 episodes it's a big time commitment. If you only have time to watch one season, Season 1 is among the best whole seasons of television I've ever watched, up there with 24 Season 1, Chuck Season 2, and Lost Season 1. It follows Veronica Mars, daughter of a P.I. and former star sheriff, as she tries to crack the case of her murdered best friend. Veronica Mars was Kristen Bell's star-making role and it saddens me to see her reduced to one-note movie roles like in When in Rome and You Again. This girl can handle so much more than rom-coms! I hope she comes back to television to tackle some meaty roles worthy of her spunk soon.
