I think that my reviews should be informative, entertaining, and fun. My reviews should contain sentences hereto unimagined by man, and if imagined, promptly discarded as unacceptable. My reviews should be a bit longer, covering more topics.
Part of writing these reviews is to get the writing practice in. Talking about something is a skill that you use all the time in stories, so if I'm going to do this, I may as well learn to make the prose interesting and engaging.
