Matthew Holness is excellent, Mitchell & Webb are great, I'd say that the only thing holding back this series is the pacing. ..& the fact that some sketches just aren't funny. Also the sketches are repeated a few too many times, particularly the unfunny ones (well, all of them are repeated too many times, even the good ones.) I wish that, while making the series, they would have gone to test audiences to find out which sketches really worked & which ones ought to have been a one time gag,... rather than returning to that dried up old cow for milk so many times when, to be honest, it was pumping nothing but sandy powdered milk to begin with.
If you want to see some of your favorite comedic actors before they realy broke into the industry, then go for it. ..Otherwise.. This series is more fail than it is win.
