The critics have spoken on Larry David’s Fish in the Dark.
The New York Times: …set postures, lines and deliveries, while throwaway humor has been exaggerated in ways that perversely shrink its impact.
The New Yorker: …sour-voiced schtick…a cynical manipulation of sentimentality and humor.
It’s not as if Larry David made any highfalutin’ claims. “I saw Nora Ephron’s play, Lucky Guy. I just thought, ‘That must be a really interesting thing to do.”
The hate from New York’s papers is perhaps best summed up by the theater critic in Alejandro González Iñárritu’s Birdman: I’m gonna turn in the worst review anyone has ever read and I’m gonna close your play. 
Luckily, the real-life critics aren’t having so much luck. Larry David’s play has broken box office records and been greeted by constant laughs and ovations every night. 

“Critics” they’re no different than the Sports “reporters” you railed on recently. Opinionated idiots with little to offer but their narrow minded opinions.
Sad but true.
