Someone commented recently that Mitchell and Webb might have been the last decent sketch show. That and Armstrong & Miller possibly topped off the long stream of sketch shows from Python through NTNON to The Fast Show, Smack the Pony and Big Train.
But there are good sketch shows online. Foil Arms and Hog is good. The one that I can’t get enough of and which is really productive with new sketches and varieties is Viva La Dirt League.
Ostensibly for the gaming community, it really reaches beyond that bringing the culture and character development, in a similar way that Spaced did, albeit in Tick Tock length episodelets. A sample supercut will be posted in the first comment.
Let me know if you know/ like it or if you have any other favourites to recommend.
