So another show that you should be watching is BSG. For those of you not in the know that stands for Battlestar Galatica. This is the last season for this show and if you haven't seen an episode yet you should start from the beginning. There are plenty of reasons why you should watch it but if you're worried that you couldn't watch a scifi show just know that it doesn't rely on lasers and aliens but rather dialogue and a deep plot.
One of the shows producers, Ronald Moore, has a political science degree from Cornell which really shines through in the pilot as well as the first 2 seasons. The bring up some sensitive topics that were and are still current but do it in a what that isn't a blatant ploy but an intelligent social commentary. Now that they are on season 4 they will tie everything up and end the series. This season started off so strong that I dropped a beer all over myself within the first 5 minutes of the season premiere and could only say, "No fucking way!!".
There's a lot of promise to this show and I'm sad to see it leave. I watch enough TV for 2 people and I can only wish that more series were written with such purpose. Any way here's a clip from Letterman before the start of this season. You need to check it out.
