Ah, middle school. What a time to be alive! A time when we were at our most hilariously awkward, as puberty assaulted us like, well, a monster. Or, at least, that’s the idea of “Big Mouth,” a hilarious new animated comedy that hit Netflix Sept. 29. “Big Mouth” follows two friends, Nick Birch (Nick Kroll) and Andrew Glouberman (John Mulaney), whose middle school misadventures are based on the tween years of Kroll and series co-creator Andrew Goldberg.
