I'm Yours! Or: Deranged by Love. In Precarious Theatre's original production, it's all fun and games until people start singing. Freely adapted from an episode in Don Quixote, the show concerns two pairs of young lovers who stumble through a long series of misunderstandings and mistaken identities en route to true love. (The plot wouldn't be out of place in Shakespeare, and in fact served as the basis for a lost play he possibly co-wrote.) There's much to admire here, from Christian Cagigal's ingenious puppet work to the precise, energetic performances by the cast. The problem is that writer and director Matthew Graham Smith decided a mere romantic comedy wasn't enough — what we really needed, apparently, was a musical. That's a shame, because from the unnecessary opening number to the uninspired love songs, the original music by H.P. Mendoza (Colma: The Musical) is far too earnest and conventional for an otherwise irreverent and inventive play. Almost every time somebody starts singing, the show's tone and pace get thrown out of whack; it would have been better for everyone involved to drop the musical and just focus on the comedy. Through October 25 at Exit Theatre, 156 Eddy (at Taylor), S.F. Tickets are $10-$30; call 800-838-3006 or visit www.precarioustheatre.com. (Chris Jensen) Reviewed Oct. 15.
