Has anyone ever come across an alien sort - extratessrial - setting either in a book and/or a movie that is actually believeable. I am not talking of colonizing another planet by humans - given how the space agencies are working, that isn't anytime in the near future. I am talking aliens coming to our world? Not in a setting like War of the Worlds - fantstic but 1950s when Area 51 was till hype - but something more futuristic / present setting.
