LOTR:ROTK
Today I started watching the 3rd LOTR movie, Return of the king. Out of the three, I think I like the two towers the best for some reason, mainly because of the magic they did to produce the CG characters.
I made it about 2.5 hours in to the film before heading over to my friends house, where we watched the first 4 or so episodes of battlestar galactica. For sci-fi films, I got in to ST:TNG the most, because I think they did a good balance of the technology and character aspects of the show. For battlestar, it is almost like watching a soap opera at times.
