The audience laughter is fairly muted from what I saw, given that these were all FANS of hers who PAID to see her.
It's not a random assortment of people off the street.
The "I'm a vulgar female, so therefore I'm funny" act is played out.
She was at her best when she did her "Inside Amy Schumer" series, where at least the skits were more self-effacing and less aboout gratuitous vulgarity.
Now her humor is pretty much, "I'm a slut, my vagina smells, men are gross, Donald Trump is a Nazi, and I'm fat."
Not funny.
