I apply my own meaning to the 5-star rating, and find it to work really well: 1 = The movie was so bad I didn't/couldn't finish watching it. 2 = I watched it all, but didn't enjoy it and wouldn't recommend it to anyone. 3 = The movie was worth watching once, but I have no interest in watching it again. 4 = I enjoyed it, and would enjoy watching it again if it came up. I'd recommend it. 5 = a great movie -- I could enjoy watching it many times, and highly recommend it.
