I think you should give the review a title, and then a gimmick reviewing system. For example, Channel 5's "The Gadget Show" uses a system of "G's" for rating, and I'm not talking abough Dre, Snoop, DOC and Ice Cube giving their opinion; it's more like "I'll give the new Nokie N97 4 out of 5 G's, it's great, but it's just lacking some features that the iPhone 3GS has".
It's fun to review stuff, but you do need to add pro's and cons if you're adding a rating system.
You should check out Ben Croshaw and Charlie Brooker for inspiration and reference.
