Or it could mean that I bought them despite being too broke to spend any money on stuff like that :lol:
nah, back then money really wasn't the problem. Fact is, the show was a pain to watch on german TV, and after the first 3 seasons there was a break of half a year or so (I thought the show was over, what with Sheridan blowing himself and the shadow city to pieces), and I missed the continuation. But since I really wanted to know what will happen next, I had to buy the DVDs.
No other show ever gave me the feeling that I'm really missing out on something important if I didn't see every single episode, so no other show ever compelled me to buy it.
The fifth season was kind of superfluous, though.
