Parasite: I second this recommendation. it's an instant classic for me. A combination of humor, violence, and class commentary.

Dune 1 & 2: Release yourself from the worries of logical plot holes and enter the beautiful world of Dune, give in to the spice.

Interstellar: Great time bending sci-fi.

Pig: Nic Cage and a truffle pig, and it's so good.
