Is Oldboy horror?

[FreddysFingers]

And that's kinda the quandry. In the case of movies like "Oldboy" or something like "The Silence of the Lambs", those movies could both be called thrillers or crime dramas, but there are plenty of genre folks who would call them both horror movies.

Is there a right or wrong here?

I don't consider them horror but the genre folks are either A) just thinking it's either one or the other and no compromises B) they want to credit more films to the horror genre. Some people would consider the remake of The Mummy a horror movie when it's obvious that it's action/adventure. Pirates of the Caribbean has gotten the horror thing as well.
