Secret Window - Yes I know we're a little behind the times. I enjoyed it right up until the ending.
It smacks of typical disposable storytelling, something not meant to be thought about or dwelt on at all. Like a campfire story that's forgotten as soon as the next one begins.
Something I've always associated with Steven King. His short stories and novellas at any rate. (Secret Window was based on a Steven King novella, in case you were wondering what the connection was.)
