That tone is useless if you're trying to convince someone who disagrees with you to change their mind.
I don't think that's the point though. The point is to get the attention of someone who already agrees with you. You thought it was bad? Let me tell you how it's even worse! You thought it was good? Let me tell you how it's amazing!
Honestly I like it well enough myself though I get annoyed when the people writing in this style drift into trying to make the argument of the opposing view in order to disagree with it. When I know a small amount of that opposing viewpoint and I hear it described so poorly... it can take me out of the moment.
