Hey Richard! I watched Goodbye World with a tremendous amount of deja vu, and eventually realised I'd seen it before. It made a much different impression on me this time now that I'm a doomer. I think they did a good job of portraying some of the challenges of surviving the collapse of civilisation. I like the conclusion that the only way we survive is by working together as a community. Not a great movie, as you said, but not bad. Worth a watch or two!
