This show is refreshing. The characters, especially Mayim Bialik as Kat, are played wonderfully by an awesome cast, each actor bringing to plate the unique quirkiness of their character--especially Sam! I also find the show more entertaining than the original BBC show Miranda, which is what Kat is based on.
13 episodes is not enough time for this show to prove itself. This is pretty much the only show I watch on FOX. If FOX cancels Kat I would encourage ABC to pick it up.
