Summer might be around the corner, but winter has finally come to HBO. On Sunday night, Game of Thrones made its highly anticipated return by launching its eighth season for a final stretch of six episodes.

Now, following the premiere, the series' Season 8 already has a fiery Rotten Tomatoes score of 97%.

While Rotten Tomatoes score for movies is absolute, it's actually different for television shows: the percentage will fluctuate as more episodes are released, and a final rating will be given only when the season comes to a close.

Therefore, after one episode, Season 8 of Game of Thrones has an incredibly impressive score of 97% -- but that number will change in the coming weeks.

For comparison's sake, 2017's Season 7 ended up with a 93% score. Season 4 stands as the highest rated season ever of the series with a score of 97%, while Season 1 is the lowest at a still formidable 91%.
