In reply to your "word" of advice. Its a review,its NOT an adaptation. This is a social network its not dictatorship. Even in real life you don't need permission to review another person's work. If not,you can imagine how many letters these famous writers would get. It doesn't work that way. The reviewer didn't write about the work,he gave his/her opinion on the work. You don't need permission to have an opinion. Have a great day too!
