I like apocalyptic movies. I guess the pitch was Tom hanks meets new Wilson, a dog and a robot meets new island apocalyptic US meets going back home driving to San Francisco. Perhaps a bit long. I would cut some scenes not needed and keep the fun stuff. UV rays works strangely in some parts of the movie. But if you don’t care about that enjoy the film. If you like Tom Hanks you will it enjoy too. It has Tom Hanks written all over it.
