Great article today at The Bitter Scriptreader about the ol’ dream cliché:
Take note, writers. There are few things you could do that convince me more of your hackitude than having a cop-out ending where everything is revealed as “just a dream.” From where I sit, it completely guts the story on an emotional level because then nothing that happened in the movie “mattered.” There were no rules for anything that happened. Plus, it’s often a cheap out for a writer trying to surprise the audience.
