"ALF" is an 80's sitcom about an annoying alien living with a normal family. It was my favorite show when I was young, and I've enjoyed revisiting it on TVD even though it declined severely towards the end of its run. The DVD sets have issues you'll want to know about so check out my reviews. I haven't gotten around to all the seasons. I jumped ahead to number 4 because of the severe issues I thought other buyers needed to know about. I plan to get to the other seasons eventually.
