I'm a big fan of movies where a person or small number of people are the only ones left on the entire planet so it was natural to want to see this film. There were interesting parts along the way and I would have given it a higher rating except the ending was, frankly, terrible. It didn't resolve anything or if it did, it was in a metaphorical sense that went over my head. I don't plan on rewatching it to figure that out. I suggest you don't waste your time either.
