One of my favourite shows right now, not in a cutesy way, but just genuinely 10 minutes of gold and very rarely a dud episode.

Just started watching the forth season with the Exit 9B two-parter, looks like they're stepping it up a notch in terms of scale.

Favourite episodes? Can't find complete episodes for streaming, but:

A Bunch Of Baby Ducks
The Power
Party Pete

all great.
