Well, in this case it's not, because criticizing the "overall concept" of a critical analysis (I prefer that approach over "fanboy rebuttals" ;) of a movie review is inherently and utterly fallacious.
Just as it so happens, it's actually a very frequently fanboy tactic to defend something from criticism - i.e. "the critic has no life spending all that time on it lol, Jorge/RLM/Lars Ulrich are so awesome anyway and won't care, and so won't anyone else", and it's very hard NOT to make associations like these immediately.
Also, saying that "I'm not gonna read it cuz its boring, and the original thing is fun and entertaining" is basically just saying "I'm not bothering to look at it if the author doesn't go out of his way to serve me hilarious fun and jokes so I bother to look at his critical analysis". Well, then... don't. When I'm writing my posts, I'm also not bending over backwards to include funny .jpgs and hilarious puns and references just to give people any reason to read them, and frankly, neither do most other forum users either here, or anywhere else. Not interested in the topic / angle - don't read. Simple.
That sort of argument says a lot more about yourself than the object in question.
