So Bad It's Good/Theatre

Examples of So Bad It's Good in Theatre include:

The Musical adaptation of Stephen King's Carrie has acquired this reputation. Its commercial failure on Broadway became so notorious that it was the inspiration for the book Not Since Carrie, a chronicle of Broadway musical flops of the latter half of the twentieth century. (King himself reportedly liked it, though.)
- Within the show itself, the pinnacle of accidental hilarity has to be "Don't Waste the Moon", a retread of the old "girls want relationships, boys want sex" chestnut with awesomely lame lyrics like "We would go bowling if you really cared / But you don't! ("I do!") You don't!"
Show Within a Show example: "Pyramus and Thisbe" in A Midsummer Night's Dream. It's so badly written and wretchedly performed that it's hilarious. The Duke and his guests order it performed just for the Snark Bait.
Robert Coates was such an infamously bad actor people would flock to see him just to see how bad he was.
From the Dream Team of Bono, The Edge and Julie Taymor comes the legendarily Troubled Production of Spider-Man: Turn Off the Dark!
