As game of thrones ends critics hail game of trolls

I think there may be some confusion here!

Game of Thrones, the popular HBO fantasy drama series, has indeed concluded its eight-season run. However, I'm not aware of any critics hailing a show called "Game of Trolls".

It's possible that you may be thinking of a different show or a parody/spoof of Game of Thrones with a similar title. Alternatively, you might be joking about the show's conclusion being so divisive that it's been rebranded as "Game of Trolls"!

If you could provide more context or clarify what you mean by "Game of Trolls", I'd be happy to help you out!
