I'm also a fan of the late 80's/early 90's cast.  Dana Carvey's "Grumpy Old Man"; Rob Schneider's "Richmeister"; Jan Hooks as Hillary Clinton; among others.  I started watching for a while again around 1995 when they added new cast members like Jim Breuer and Molly Shannon.

I've been watching the current season, which has been hit or miss, but I still enjoy it overall.  I have to say that my favorite current cast member is Nasim Pedrad, who is badly under-used.  A really cute and charming performer.
