I almost refused to start watching the show because of my memories of the original and how bad it was. Then one day they had a re-run marathon on HDNet and I caught a few episodes. I determined that the show was bad bellybutton and soon downloaded the first season and caught up on the second season. Its been my favorite TV show ever since. I've since bought the DVDs for all 3 seasons and I hope they come out on Blu Ray some time soon. I've even bought the Original Sound Tracks for each season and my World of Warcraft PvP video is set to BSG music (much better than the same 4 songs all other WoW videos the kiddies set them to).
I've got a pool going at work for who the 5th of the final five turns out to be. From the info that's come out during this mid 4th season break, I have a feeling there's going to be no winner though.
My favorite episode is still 33, its strange that the first episode after the pilot was so well conceived and executed. But the 4th episode in season 3 where they escape from New Caprica is my second favorite, and it just so happens to contain the best special effects sequence in the history of the small screen, imo. A great, great episode.
