Seat Filler: The Advocate's Guide to New York Theater 

Bonnie & Clyde
Laura Osnes and Jeremy Jordan sparkle and smolder as Depression-era outlaws Bonnie Parker and Clyde Barrow in a paint-by-numbers musical that also stars hunky out actor Claybourne Elder as Clyde’s brother. The show ultimately whimpers despite lots of fake-bloody bangs — Clyde bludgeons a fellow prisoner who made him his bitch — and a rockabilly- and blues-influenced score that’s Frank Wildhorn’s best since Jekyll & Hyde.
Gerald Schoenfeld Theatre, through December 30.

Seminar
Teresa Rebeck’s smart and satisfying comedy stars the effortlessly commanding Alan Rickman — best known as Snape in the Harry Potter films — as a slimy author teaching a private seminar for young writers. Jerry O’Connell makes a solid Broadway debut as a pretentious prep, and American Horror Story’s Lily Rabe steals scenes as a rich girl taken seriously only when she pretends her work is by “a cross-dressing Cubano gang member.”
John Golden Theatre, open-ended.
