[Mad Melvin]

I liked saturday night live back in the Dana Carvey/Chris Farley/Adam Sandler/Phil Hartman/David Spade era, but nowadays its just boring and unfunny.
MadTV has a few good sketches(Steven Seagal show!), but overall its not that good.

I dont know about the other shows you mentioned.

In Finland theres currently a few sketch shows running: Saturday Night Live, MadTV, The Fast Show and Gavin Crawford show.
