Not seen them all but my picks: Mandy, Malignant, Spontaneous, Pig, Bullet Train and One Cut of the Dead. I have, or will soon have, them all on disc and recommended them to anyone that stands stil long enough near me.
Some others are in my watchlist and I am intrigued enough (from what I've seen nothing is terrible, some just didn't land with me, like Pearl) to give them all a spin.
