seppelfred: The first reply in this thread mentioned The Others.
KoreaBeat: Oops, I read right over it!
Anyway, trick endings are fine, but not when they get to feel obligatory. I think the fake-out ending that sets up a sequel is actually worse.
The problem with The Others is that it came out at approximately the same time as Sixth Sense. That ending has been used for ages, and with good effect, but with two major movies using it at almost the same time it was a mess, and The Others was unlucky enough to be the 2nd one into the party making it look like the copycat which probably isn't very fair.
