Edge: This one-woman show about the tormented life of poet Sylvia Plath features a startling, riveting performance by Angelica Torn that blazes as fiercely as Plath's poetry. Paul Alexander's play depicts Plath's failed romances and suicide attempts, and excoriates her husband Ted Hughes as a controlling monster who profited mightily from her royalties after her death. Despite these fireworks and a welcome dose of wry humor, this tale of rage and obsession feels rather flat dramatically. Edge works best as a performance showcase for the splendid Torn. -- Ronald Mangravite Through March 27. Coconut Grove Playhouse, 3500 Main Hwy., Miami; 305-442-4000.
Stones in His Pockets: Marie Jones's play centers on a small Irish town in picturesque County Kerry which is invaded by a major Hollywood film production. This clash of movie types and locals offers a colorful array of characters, all played by two resourceful Irish actors, George C. Heslin and Declan Mooney. The two-man concept has theatrical appeal but there are costs -- Michael Hall's production is quick and deft but some of the characters are mere caricatures, and much of the play's emotional texture is missing. -- Ronald Mangravite Through April 3. Caldwell Theatre Company, 7873 N. Federal Hwy., Boca Raton; 561-241-7432.
The Diaries: This mess of a play begins with the suggestion of something much better. A young American scholar is about to give a talk on campus on the subject of his Nazi grandfather's diaries, controversial documents that may be either a monster's apology or the candid testimony of a moralist caught in unspeakably immoral times. This is promising stuff. And a great play might be written on these themes. John Strand's silly affair, directed by Rafael de Acha, is not it. -- Octavio Roca Through April 3. The New Theatre, 4120 Laguna St., Coral Gables; 305-443-5909.
