I can see how it is harmful to have threads about how bad an actor is, when they have worked tremendously hard on their part, etc. ("I hate so and so..") But constructive criticism is another story. It is judging solely on their performance, and what their faults were. Nothing wrong with that.
Sorry Josh, but you need to learn to accept some negative reviews. A person has the right to judge a show, and their experience with it. If a person looks into what people are saying about a show they can determine if the particular show is their taste and to their liking. That is what message boards are for.
So afraid of getting older
I'm only good at being young
