Haha, funny show is this one. Our hairy extraterrestrial being chasing the family's cat to eat it was always a laugh, how about the times when his ideas were misunderstood by his human friends? That was pretty much everyday life for Alf and pretty much the basis for all the episodes in this sitcom. The humor is there and the jokes are clean you don't have to worry about anything, this is humor for all the family.
In the bottom of my mind i was always wishing for Alf to be caught but they never did, fully. Fun and clean, what else do you need? you don't find this kind of sitcom anymore.
