Bullshit. I find that user reviews and critic reviews often diverge in the same way that an Adam Sandler movie is never going to win an Oscar even if it is popular with theatergoers, but that's fine. In fact, I find it really useful to categorize movie reviews as:
* High critic score, high audience score - OK, why did everybody love this movie?
* High critic score, low audience score - usually a more "niche" or academic topic, definitely something that will make me think, even if I don't like the movie.
* Low critic score, high audience score - A "turn my brain off and enjoy it" kind of movie.
Critics, aka online blog journalists, are paid to generate content. The goal of that is to get you to click on it to look at an ad, either by getting you angry at it or just by producing tons of it so you'll read it all.
Complimenting people doesn't come into it - who do you think is going to pay them for that? Amazon's not going to block them from watching the show.
