Twist endings only [THIS] movie could pull off?

[X-Nightcrawler]

What movie has a twist ending that you wouldn't tolerate in any movie . . . but it somehow worked for this.

I don't think I coul've stood the 'it was all a joke' in any other movie but I LOVED it in this movie.

Definitely APRIL FOOL'S DAY. No other horror film pulled off the elaborate hoax that this film did...in spades!

I think I am one of the few people who did not like April Fools Day, and I didn't like it BECAUSE of the ending, that it was just plain stupid. I still own it though

Undead. If you've seen it, you'll know what I'm talking about.

Anguish for sure.
