I'm not sure what your point is about game-breaking bugs and reviews. If the reviewer runs into one, sure, but they probably won't, as they typically only affect a relatively small amount of people. The more complex a game, the more likely it is that devastating bugs will be missed.
Also, you say "sod graphics" then complain about graphics. Which is it?
Anyway, what you're really saying here is that developers should stop making complicated open-world games. The Witcher 3 was filled with bugs, including the game-breaking variety. What do you think it should have been scored? Do you think they should have made a linear yet polished game instead? If the game had scored low and it killed The Witcher franchise, would you have been happy with that?
