I really enjoyed "Her", especially how pretty it was. "The Hunt" is definitely up there too, as can be expected of glorious Mads Mikkelsen in his native tongue. I'm not great at remembering the impact of films though, so there maybe others that I'd deem superior if I'd seen them more recently.
I like Moty Python and the Holy Grail. there's just a comfy vibe about it plus it's hard to find good movies about King Arthur. I enjoy watching shit that's so bad, it's good like The Room, Birdemic, Fateful Findings and Cool Cat Saves The Kids.
