Commenters on TheTvCritic.org tend to fall into two camps; those who buy into the system (including me), and those who don't. I think his writing style is unique, allows for in-depth analysis that, regardless of whether you agree or not, deserves respect.
Some television reviewers use letter grades, some use a 5-star rating, some use a X/10 score, but this 100 scale allows for differentiating the "good", the "really good", and the "fantastic".
Television is all about personal taste, as we all value certain components of what we watch differently. I do agree that plausibility is really important, its a major factor as to why I loved Breaking Bad and how it was a massive success.
Particularly with comedy, jokes/gags/scenes need to have a foot in reality if the show is formed upon that basis. The Simpsons is a great example, it began as a show about a family dealing with issues like grades in school (Bart gets an F) and Homer getting a heart surgery, and now I read about plots about sentient robots and dogs taking over the town. A large percentage of the site is of sitcoms; which may be the most divisive genre of television, because you either find the jokes funny or not.
It is certainly a normal human drive to want other people to like what you like, so if you love an episode of TV naturally you would want others to agree. When I first started reading TTC for instance, TTC hated "Dinner Party"; an episode of The Office, which is one of my favorites of the series. His criticisms explained why he didn't like it to my satisfaction; it didn't change my opinion of the episode but I could respect that someone had a different perspective and it enriched my television viewing experience.
Debate can be fun with television, some of my favorite content on the site are from the episodes that sparked the biggest debates/controversy (Get The Girl, The Same Boat, Lost season 6, Flashforward).
