What makes for a good review?

[Hinterscher]

I don't know if this goes here or not, but I'm sure it will be moved to the right place. I've been getting my feet wet doing a handful of reviews and a few of them have really taken off and I've gotten lots of really good feedback and a few of them have completely tanked. So, I'm asking, what do people want? I enjoy doing reviews, but I want the people watching them to enjoy them to and take something away from it. I try to give what I appreciate from watching others reviews, as much as I can. But I also want to know what's helpful to others, too. Short and sweet, just the basics, or more in depth? Just in general, what makes a review good to you. Of course, with the exception of one, have been on kits I've bought myself, that's not the question. Just in case someone thinks I'm greedy. I'm just honestly hoping that some veterans can give a noobie some advice and that the rest of you can just tell me what you like to see. In reviews that is. Thanks to anyone willing to help me out!
