i totally loved this show!
instead of all the other sci-fi- or fantasy-centered sitcoms (like for example sabrina) this one didn't rely on heavy special effects. instead, the "alien" feeling came through the actors performance. it was exaggerated, sure, but in a very VERY good way. my favorite episodes where the ones where harry turned into a transmitter. in one of the last episodes he transmits an alien-award show and you can see him dance on behalf of the ballet. when you look closely you can even see kristen johnston (sally) nearly fall out of character. it was so hilarious, you could see her biting the insides of her cheeks not to start laughing and ruining the scene. and my favorite dialog was her asking dick "why am i the woman"-"because you lost".
great.
