I've had to think this cuz there were bad endings I've seen...but Fear DOT Com takes the cake. The movie was kinda cool if u were a horror fan, and they hadn't made a film like it in a while....

but then [spoiler] The good cop get shot saving the girl  and is dying and they cut to the main girl with her cat on the bed....and that's it? WTF?!

Worst ending for me would have to be...

The Lord of The Rings: The Return of The King.

It ended completely wrong, although it was good i wanted it to be like in the book.

The Usual Suspects.

The Lord of The Rings: The Return of The King - the ending just dragged
and horror movies that leaves no one alive it just annoys me i mean whats the point of watching it if there all going to die

Ummm... that spoiler isn't blacked out...

Say what?   That had a fantastic end.

Worst ending?    Student Confidential.   Try and top that one.

my job is done .

Starship Troopers.....

At the end their are all standing round laughing, cheering and joking and forgetting that hundreds of thousands of people have just been killed by massive insect type creatures that eat humans alive

Like a human wouldn't poo themselfs at the sight of one of theses monsters.

The Andromedia Strain - at least the book....

i dunno. i thought dumbledore dying was a pretty stupid ending.
