Broadway Play 'Good Night, Oscar' Struggles to Capture Legendary Musician's Genius or Soul

The play is set in 1958, focusing on comedian and musician Oscar Levant.
The play relies too heavily on Levant's famous witticisms rather than insight into his life and talent.
Sean Hayes gives an accurate performance as the troubled Levant, but the role lacks depth.
The play aims to reveal Levant's inner self in its ending, but overall fails to make a compelling case for his brilliance.
Critics find the play unconvincing in its portrait of the complex show business figure Oscar Levant.
