Dylan Schnabel’s review published on Letterboxd:
100% Fresh is exactly that. It's a fresh stand-up experience from Adam Sandler that goes back to his musical comedy roots.
The best part? It's actually funny. 100% Fresh is Sandler at his best. He's a bit rude, he sings almost all of his jokes, and he makes you crack a smile.
The format of the special is a bit strange, though. Instead of a single show filmed continuously to make up a special, 100% Fresh is made up of multiple different shows stitched together to create the special.
Even with the unconventional format, the special is a fun piece of work, and it's certainly Sandler's best with Netflix so far.
