People always shred the critics because they see the movie first and evaluate their opinions on it. So they are the first ones to get the anger, stubbornness and rage from everybody. No one is forcing anyone to listen to them only. You take their opinion, combine it with your own thoughts, gut feelings and evaluation then you decide if it is worth your time or not. And many times the critic's evaluation is right on the money but rage and stubbornness always take precedence over common sense and even a person's own eyes or ears. People want the critics to say what they want to hear not what their opinion is. If they say what people want it's fine. People cheer them on and boast to everyone about their praise. But the moment they look down on anything that people wanted to be good or thought would be at least average suddenly critics are idiots and don't know what they are talking about. Just watch. If Batman Vs Superman ends up less than average and the critics don't hold back on it,the comments will flow in how stupid critics are and how they are just a bunch of Marvel movie lovers. But if they give it nothing but praise suddenly critics are great again.
