ALF

I think that Alf ended on such a sad note, I avoid watching the last episode. I've seen it , but no where near as many times as the other episodes. In the last episode the alien task force is closing in. The Tanners can't get to Alf and save him. You know he is going to get captured.

After the series ended, I know there were one or two Alf TV movies, not featuring the Tanners.  They are mentioned in one of them.  The one where Alf is  in some sort of military setting maybe the air force, after having been taken by the alien task force.  Alf escapes, causes minor/major mayhem.  Okay movie, but not as good as the series.  I'm pretty sure there was another movie, but can't remember anything about it.
