The last three seasons of Game of Thrones was rubbish though.Ep 3 also got about twice as many 10 scores as the previous two episodes. If it was review-bombed it was also review-highed. Then there's IMDB weighted average algorithm which they don't disclose. The true average for the episode was 7 but IMDB adjusted it to 8.
The show isn't at the level of great shows like True Detective S1, GoT, Breaking Bad - so the 10 scores are a bit silly.
