Slings and Arrows is a great show. A Canadian production, the show is the story of an already slightly mad actor/art director who oversees the Shakespeare festival at a local theatre, sees the ghost of his mentor/predecessor, has to work with his ex, and has to deal with corporatization of the arts. It's all great (and so... Canadian!), both hilarious and heartrending at the same time.
Each season of the show has the theatre focusing on a different Shakespeare play (Hamlet, Macbeth, King Lear) and one other play; the story-within-a-story arc is great, with the casts of the different plays squaring off against each other, castmembers of the same play squaring off against each other, actors holding a thin gold line against management, and funders and board members trying to meddle with Art.
It's too bad the third season was the last. Each season was only six episodes, too, so it really was short-lived.
