To leave your opinion in the review, to actually, concisely, express an opinion within the review itself and not just "Good, forgettable, but good", that's just a basic summary.
To actually pay attention to detail and to contribute to the work in question by critiquing it on certain details and to constructively give advise, to ask questions about plot holes and to point out flaws.
Not to just express your opinion in a single phrase but to elaborate on what you thought was wrong, where improvements could be made and just things in particular.
Not to attack the content but to criticize the quality of the content, not the story but rather the way it was executed, not the dynamic the animation follows but how well it follows the dynamic.
To weigh the value of something by it's quality and not it's content.
In otherwords, to actually give a shit to contribute to the improvement of someone else's work, skills and talent by expressing your own viewpoints on the subject matter, not to badger it with negative, hateful, personal, derogatory remarks aimed at the author for simply having created work in question.
That is the purpose of reviewing something.

The people who's work you're critiquing shouldn't have to read your blog to understand what your review means. That defeats the entire purpose of a review. Sadly that's not even the beginning as to why your shit eating reviews are being deleted.

What IS the purpose of a review, according to you?
