Joe Swanberg is my favourite mumblecore director. Be sure to watch all his movies you can find.
Here are some essential mumblecore films:
Funny Ha Ha / Mutual Appreciation / Beeswax by Andrew Bujalski
The Puffy Chair / Baghead by The Duplass Brothers (and their short films)
Humpday by Lynn Shelton
Yeast by Mary Bronstein
The Exploding Girl by Bradley Rust Gray
Open Five / Open Five 2 by Kentucker Audley
Momma's Man by Azazel Jacobs
Some mumblecore movies that I hated: The Color Wheel, Harmony and Me, The Hole Story, You Wont Miss Me, Breaking Upwards, Four-Eyed Monsters, The Pleasure of Being Robbed, In Search of a Midnight Kiss.
Be sure to look into mumblegore as well:
Anything by Ti West
Anything by Adam Wingard
Your sarcasm is horribly out of place. I'm trying to have a serious conversation here.
Stop embarrassing yourself. Nobody's making you watch any movies you don't want to. Just stop pretending you know what you're talking about.
