It's called expressing an opinion and anyone is entitled to do it.
Indeed - but what's it worth? In our capitalist world the value of nil must be the answer - as your reviewers are undistinguished and unpaid and no one will pay to read them and hardly anyone looks at them unlike established press. Vanity it is and without influence or importance.
I’m curious as to why you bother to contribute to this forum seeing as you are so hostile to the concept of on-line dance discussion.
There are over 200,000 postings here with many single topics having been read by tens of thousands of ballet fans and a fair number of dancers. Anyone may post a review here and yes, a few can be described as “undistinguished” but all serve the purpose of bringing experiences of dance performance to ballet lovers across the globe, something that the “established press”, which rarely allows its critics more an a couple of paragraphs, doesn’t do. National daily papers are therefore unable to cover the ballet scene worldwide, whereas this website attempts to do just that.
Actually some of the reviewers here are also contributors to both the dance press and to national newspapers, something you would be aware of if you took the trouble to read the forum thoroughly before posting.
