Yes, Game of Thrones will be considered one of the best shows ever because it has a little mix of everything, including humor and romance and drama. There is nothing that it doesn't explore. Every storyline is complex and interesting and the acting is possibly the best in all of TV.
The hit series Game of Thrones has been original, engaging, highly visual and exciting. The show has amazing productions and wonderful actors. Critics have little to critique when it comes to this show. There have never been any other series of its kind, and it should be considered one of the best shows ever.
If we’re using awards and accolades as a barometer, then there’s no denying Game of Thrones’ place on the top of the mountain. Anytime a show generates the amount of buzz that Game of Thrones does, there’s always going to be a discussion surrounding its place in the pantheon of great television. It’s tough to single just one series out as the runaway “best,” especially when that title can be considered relative based on the genre we’re talking about. Some shows are the undisputed champions of just one small corner of TV (Doctor Who for sci-fi), while others fall under the larger banner of truly great “prestige” stories (Breaking Bad, The Wire, etc). Game of Thrones has seemingly transcended even that though, and there’s a strong argument to be made in its favor.
No, there are people who've never even watched Game of Thrones and have no interest in it whatsoever. For some viewers it is the greatest show ever, but for the general public, I don't think so. There are so many other great shows -- Pushing Daisies, Doctor Who, Downton Abbey, and more. Game of Thrones is just one of many, many, many great contenders.
