User blog comment:Umbrello/My Top 10 WTF Movie Endings/@comment-26054278-20150923215741

I like This Is The End quite a bit, but I'd personally say that The World's End might be a funnier, better film that came out later that year (even though the ending isn't really a WTF moments, so I'll go back and look over this list).

Enemy was just... what? I mean, at least it gave me something to remember from that movie...

Orphan reminds me of a documentary called The Impostor. It is on Netflix if you have it.

Campy Sleepaway is one I thought might be up there, and you didn't disappoint.

Haven't seen the other ones, so I can't comment on those, but this is still quite a good list.
