It starts off with a man failing at hanging himself from a fruit tree in a bleak-looking garden. Something this grotesque isn’t usually the stuff of sitcoms. This is unsurprising because Will Sharpe’s Flowers, produced for the British Channel 4, is not your usual sitcom. With a unique visual style, an extraordinary cast, and a dark, satirical script, it carves out a genre of its own. The always amazing Olivia Colman plays Deborah Flowers, the eccentric family’s matriarch, and a music teacher. The man trying to hang himself is her depressed and unfaithful husband Maurice (Julian Barratt), who is a children’s book author. They live in a ramshackle house with a Japanese butler, who barely speaks English, and their dysfunctional adult twins. Amidst all this glorious mess, Flowers is ultimately about mental illness and depression and is apt in pairing this disturbing reality with hilarity. Obviously, it is very dark. A bit too dark for comedy, and too mad for drama: truly original stuff.
