"No, it's not good for him,"
On the contrary, it is very good for him, extremely good for him. He said all that he wanted to say, exactly how he wanted to say it, without following anyone else's cast-iron diktats on the matter. So yes, that is very good for him.
"nor is it good for anyone else."
Well, Jimmy, I can't speak for anyone else, but I can assure you it is very good for me. I would much rather read a person's honest assessment of a show in one sentence, or even one word, than the pompous, self-important, doctoral-dissertation-length disquisitions of some pretentious know-it-all. So yes, please, let us have more posts like Stevie's and less of the insufferable windbags'.
"I don't care whether someone likes or dislikes something, but one should be able to tell others why they liked or disliked it."
And what if one is perfectly able to tell why but just doesn't feel like it? This board is a recreation, not an obligation. One should be able to say as little or as much as one pleases. Three cheers to those who say little!
The fact is all this whining, "you didn't give sufficient reasons," or "it's your tone I object to" is just so much hooey.
If Stevie had posted a one-sentence post exclaiming Hamilton to be the greatest show he had ever seen, do you think any of the show's cheerleaders would have sought to discredit him for his failure to provide reasons why?
