Have you seen it yet? This is not something to miss! Personally I love the music, but the real charm is the humor. Neil Patrick Harris is the perfect comic hero/villain.
If you've not heard of this show, it's a little ditty by Firefly and Buffy creator Joss Whedon and cohorts, created as something to do while the writer's strike stalled all production in Hollywood.
Once upon a time, all the writers in the forest got very mad with the Forest Kings and declared a work-stoppage. The forest creatures were all sad; the mushrooms did not dance, the elderberries gave no juice for the festival wines, and the Teamsters were kinda pissed. (They were very polite about it, though.) During this work-stoppage, many writers tried to form partnerships for outside funding to create new work that circumvented the Forest King system.
