I know. Sometimes you have to wonder what the purpose is behind those award shows and how much of a win is due to merit vs internal politics. Part of the problem is that there's no objective way to measure the quality of a movie. If there was everyone would try to use that formula.
Personally I don't like movies where the setting is some time when civilization falls, but Postman is about someone performing a governmental service and I can get behind that. I also wonder if a movie about how good an important a non-military government service can be was part of why people didn't like it.
