I don't know, I don't think it's the same thing. But I think that's probably because after watching Kieslowski's films - especially the colours trilogy - I completely changed my concept about anti-comedy, anti-romance, anti-tragedy, etc. Because Kieslowski inverts everything in his anti- films. It's not just atypical, you know, it's totally inverted. So I guess that affected my concept of these anti- films. So, yeah, maybe 500 Days of Summer is an anti-romantic-comedy, just not Kieslowski-like, because I can't expect all anti- films to be like Kieslowski, especially because Kieslowski is incomparable.
