1) It’s entertaining. The movie is purely fun/thrilling/enjoyable to watch.
2) It’s relatable. There is something about the movie that was very easy to identify with.
3) It’s profound. It makes you think about something in a new way, or it just says something so true and tough-to-articulate about life.
4) It’s amazing to look at. The movie was visually stunning.
Of course, there are more, and these categories could be broken out into a million subcategories (which it’s a critic’s job to do), but I think these are the main ones which we can now unpack.
Of course the worst cliché movies are the ones that think they’re so absolutely brilliant and earth-shatteringly profound, when in reality, they’re just one more load of already-been-said BS. “Revolutionary Road” (directed by Sam Mendes, starring Leo DiCaprio and Kate Winslet) comes to mind, as does pretty much anything written by Charlie Kaufman.
So I suppose, what makes a movie good is having one, or maybe two of the traits listed above in moderate degree. But what makes a movie really great is when it has multiple of these traits, to a high degree.
