Absurd situations, surreal conversations, nihilism and existentialism at three o'clock in the morning. Where better to find it than in the temple of consumerism, the 24 hours convenience store?

Most of the scenes are relatively unconnected, there's not much plot development (and certainly no character development), and apart from the last episode, most of the scenes could have been swapped around without any detriment to the whole.
These unconnected skits remind me of the best of British comedy of the 1960s to 1980s in the heritage of Monty Python. The absurdity rivals skits like "The Cheese Shop" or "The Dead Parrot". It certainly wouldn't have been out of place in shows like "Not the Nine o'clock News" or "Fry and Laurie", only that the humour is, of course not in the English style but very Japanese.

The characters -- obviously caricatures -- are excellently done by the actors, and, if all of them did not have the great comedic timing they have, I'd suspect a lot of ad-libbing, this feels just so fresh and spontaneous.

You might find it too weird if you're not much into the surreal and absurd side of life, but if you are, you should give this series a try!
