That is LITERALLY the absolute worst list I've ever seen for anything.If they think Kane has the worst ending ever (which obviously they don't ...it's a sorry cry for attention) then they just need to re watch the fucking movie. From the description of the ending the writer clearly didn't understand the fucking point of the movie and the significance of the sled.
The comment on Holy Grail is pretty silly. I wonder if they actually understand the movie? The cops show up because the historian has been murdered (by the knight riding by). The ending is the punchline to that earlier gag; I've always appreciated it.
Brief Encounter (I absolutely LOVE that ending personally)?
