Man, I have to see this again... It's been so long. Great fun this movie was.
Also... I'm wondering, should I watch Battlestar Galactica? I always thought it looked ridiculous but I want a new movie to inspire me again in the space exploration type genre.
I haven't seen Razor but people tell me it actually requires no knowledge of the series to enjoy, and contains very few spoilers. Still, I can't vouch for its quality, whereas I can tell you that the 3-hour pilot, even though it started slowly, soon grew upon me. It certainly motivated me to buy the rest of the series.
You might also wanna check out Doctor Who - although the box sets for it are extreme bad value for money, so just download it all. The show varies in quality quite a lot because it's mostly a 'monster of the week' thing, with different writers, but it usually ranges somewhere from 'quite good if silly' to 'very excellent'. It contains a fair bit of space antics.
