@joandaro absolutely a bad game can have good parts but I always rate in my experience of the game. If I had a bad experience, it will get a bad rating no matter how good the graphics were. The graphics obviously didn’t lift the overall experience enough.
Many walk into the trap of trying to make reviews that are objectively true, but there are no such things. For games, it all boils down to if you had a good time. If the answer is ”no” then it doesn’t matter how good it’s supposed to be.
I had this experience with Mass Effect Andromeda. There was so much hate for that game, but I had a good time with it. I recognize some of the issues but they didn’t ruin my experience.
