In no particular order:

The X Files

Lost

Game of Thrones

*Magnum P.I. (I had *such* a crush on Tom Selleck as a kid)

Star Trek (original series but I also liked TNG. I don't like next gen anymore.)

The Kids in the Hall and In Living Color are tied for best comedy series.


* Magnum is a bit of a joke. But I watched it and the reruns constantly when I was younger.
