Unpopular as not-very-well-known or unpopular as people-think-it's-crap?
Forgotten classics:
I loved
Ohayou (directed by Ozu Yasujirou)
The original
Sleuth movie (1972) was so awesome I don't dare watch the remake, even if Caine is in it.
Supposedly crappy:
What We Do in the Shadows! It's so so so hilarious.
Frequently Asked Questions About Time Travel. As pretty much anything with Chris O'Dowd in it. He's such a funny dude.
Rom-coms that people won't admit are lovely:
Penelope. With James McAvoy and Christina Ricci.
Ever after. With Drew Barrimore being cooler than she's ever been.
And probably much more I can't remember right now
