Now that season six of HBO's "Game of Thrones" is in the can, we can see how it fared against previous seasons in the critics' eyes.

This was the show's highest-rated season to date, but that doesn't necessarily tell you much about quality. Season six could've attracted more viewers by the nature of its unpredictability. It was the first season to surpass the George R.R. Martin books the show is based on, so there was an extra curiosity factor built into the season for book fans and the show's fans.

According to Rotten Tomatoes, which assigns a score to reviews in order to give a picture of critical reception, the season was well-received.

"There were a lot of expectations on 'GoT,' since this was the first season almost entirely off-book, and most critics have agreed that the showrunners have pulled it off pretty spectacularly," Rotten Tomatoes senior editor Grae Drake said in a statement. "There's been a lot of table-setting this season, but with more characters converging, there have been fewer threads to follow, which has given them the time to focus on key storylines and move them along at a relatively brisk pace."

In the end, where did season six rank among the show's other years?

Here's the ranking of "Thrones" seasons from worst to best, according to Rotten Tomatoes scores:
