If you like good indie sci-fi make sure you see Sleep Dealer, Primer, Banshee Chapter, and Moon.
Going back further I’d add Pi.
This one’s not quite sci-fi but if you like indie and very weird and cultural references that are really deep cuts check out an indie series called Hellier. If you’d like to see some hipsters try to talk to aliens with transcranial magnetic stimulation equipment, then it’s for you. Kind of ghostsploitation meets sci-fi meets conspiracy occult weirdness, all played straight Blair Witch style. The music and cinematography are great. I’ve compared it to Primer in terms of cost/originality/quality trifecta.
