We can only hope the film is a flop, but that probably won't happen.
I just read that VARIETY's chief film critic describes the script as "flabby."
I laughed aloud when I read that.
I don't want to give the impression that I'm rejoicing in anyone's failure(s), but, as to Kushner's work particularly, yes, flabby and I sure wouldn't lend any support (nor viewing time or money) to his success.
