Another example on how to mess up an ending

Rating: 5/10 (17 August 2018)

It could have been a classic had it not been for that terrible ending. Everything was going well, the suspense between the characters, was the bunker man telling the truth? Everybody watching could not say, he looked like a man with serious psychological issues.
Now, what is this obsession with presenting aliens as some sort of prehistoric dinosaurs with a big nasty mouth eager to eat you? Does anyone think that a dinosaur like creature grinning their teeth would have the brain and the ability to build a space ship and travel through space? It's ridiculous!
