I’ve been putting off starting a thread for nominations for the worst movie premise within the constraints of that movie’s world.
My addition would have been Snowpiercer. The world has become a frozen wasteland and you have invented a perpetual machine/energy source and your great idea is to use it to power a train driving forever through the frozen world rather than do something sensible like digging into the side of a mountain and setting up the survivors there.
Imagine my surprise to find out it is being turned into a TV series.
Some people though it was a great movie so good for them.
Personally I thought the plot holes were big enough to drive trains through.
