I love the "weird" movie genre, in part because I have grown tired of the same old Hollywood plot lines that repeat ad nauseum in slightly different formats in so many movies.
A couple of my favorites were already mentioned like Donnie Darko and Memento. Christopher Nolan is one of my favorite directors largely because of how he creates unconventional movies with weird time shifts but Memento is probably his "weirdest" one. Pretty much anything by Darren Aronofsky fits the bill... Black Swan, Pi, Requiem for a Dream (best movie you only want to see once), Mother!, etc. area all pretty out there. Stanley Kubrik is another director with a few strange ones.
A few others I haven't seen mentioned:
Natural Born Killers
12 Monkeys
Pan's Labyrinth
I'm not sure if these qualify as "weird" per se, but are more unconventional movies or cult classics
Big Trouble in Little China
Dark City
The Crow
Fight Club
Ex Machina
