It's just good TV. Positive, uplifting, good values, teamwork, friendship, love, damn good CGI and other special effects. No Gore or over the top sex scenes. Episodic, yet has an overall storyline that keeps it going. John Larroquette is fantastic, I love seeing Rebecca Romijn in something of this quality, and the other actors/actresses are good as well. I love the scenes where Cassandra does her mind explosion math, and other science things. Each character gets a lot of good development, proper stories. Highly recommend.
