Battlestar is great. I watched the old series when I was little, and I remeber liking it, but it was pretty cheesy. This one is a lot more gritty and the acting is very good especially Edward James Olmos as Adama. BTW- He might be the first hispanic in TV space. The special effects are top notch. I usually am not home on Friday at 10pm, but they replay it on Monday too. I've seen every episode.
Lost, 24 and Battlestar are the only shows I regularly watch.
