The list of good movies is incredibly long, but IMO most are just that good movies are not really in the running for best movie. Take Life Is Beautiful it turned a 20m budget and 10x that at the box office in large part because it's a good movie, but not really 'the best'. Rocky horror picture show is a very different move though again popular, but not really in the running for 'the best movie of all time'.

So, while I don't think you can get a definitive list, you could get 7/10 on most peoples top ten lists out of perhaps a few hundred movies though I suspect significantly less than that.
