How did this movie got a rating over 7.0?

Rating: 3/10 (9 January 2019)

For the life of me, I can't understand this. I have rated over 3000 movies here on IMBD and this one was among the lowest scores I ever gave. And I'm not the type to give a 1 rating even if I hated some movies. I don't give a lot of 10/10, only movies that are masterpieces to me like Lord of the Rings, Star Wars, Shawshank Redemption, Harry Potter, Silence of the Lambs, Gangs of New York, Life is Beautiful, etc
