Personally, I feel that my least favorite is MCC... it's not Muppety at all... just...
well... let me put it this way. if I were to retitle it, it would be called "The Michael Cain Christmas Carol with the muppets" I'd say the same for MTI, but I feel that it has the Muppet wackiness spirit that was missing from MCC.
I really did like MFS, not as much as the older ones, and VMC was great.
Didn't get to see KSY though... been afraid too....
