they frequently have the characters use aliases based on comic book super heroes, sci fi writers, doctor who, etc.
The show is a lot of fun. The main problem with the writing is time constraint. Clever twists and no dumbstick characters requires a lot of time to distill out something original and not obvious. On a weekly show you dont always have the time to get the story to the fully polished stage. And since it is a dean devlin show, they tend to fall back on schmaltzy to make up for any suspension of disbelief.
that said, the pilot was really nice. Season 1 was a little rough and wasnt nearly as clever as the pilot. Season 2 got better fast, and 3 has been probably their best yet.
