ELF was hilarious!
I actually kinda liked Bad Santa. I consider it a 'dark comedy,' which actually had some funny parts (though I wasn't impressed enough to remember what they were), unlike other supposed 'dark comedies' which I didn't find funny at all like To Die For with Nicole Kidman. Can't think of any others.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. ... The piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
