I just never found it appealing. Seems too cheap/geeky? I am probably wrong, and I am a HUGE geek. It seemed too Star Trek and I hated the Star Trek series.
I didn't like the first few shows I saw. I couldn't stand the woman president, I had no sympathy for the guy with the blonde android or whatever she was, and all the "frack this, frack that" annoyed the hell out of me.
