Alien Nation was a late night treat for me back in the late 80's, the first episode is much like the film with human cop matt at first disliking his Alien partner George but as the series goes on matt starts to respect his partner. The series details the family life of both characters well but doesn't distract from the exciting storylines. I really like the relationship that developes between Matt and his female Alien neighbour.
The series ended on a cliffhanger and was then for some reason cancelled. A few years later 5 TV Movies were made of equal quality to the series but are not available on region 2 DVD at the momment which is a big frustration to me. So until the Movies come out I would highly recommend this DVD.
