Well I like to be able to have informations in a pretty fast manner I dislike having a single note or mention to sum it up.
101: the last (short) paragraph of the review alone should allow the reader to have precise idea about the game.
In a concise manner the last paragraph would address those three points with key words or predefined locutions.
Production value: visual quality and variety, music, dialogue/story, etc.
Execution: whatever the game pushes out does it do so smoothly
Lasting appeal: cover replay-ability content size, mp, etc.
Example:
XYZ is a racing game, heir of a long tradition of XYZ games, production value is above average, execution is flawless, the lasting appeal is great thanks to the replayable nature of the game and a MP mode than did no forgot local MP. XYZ is worthy upgrade for the fans of XYZ series and those in search for racers that packs lots MP fun including local MP.
Now there is hardly nothing new to it. The point is writing is important but reviews site are reputable in the long run due to the consistance of their rating and how pleased costumers have been with their recommandations. In this age of hype, hate, ego I think that if you want to be at tip of the trend it is time to move back to "serious" (not boring), time efficient (for the reviewers and readers alike) approach to reviews. Ultimately there is meta-critics that is competing against you and that is fast. I would make it so pretty much to read the review you don't have to scroll down the page, it should fit on the back of the box game.
Times wants that reviewers have to posture as archetypes of coolness in its many forms (lol...) opinionated, etc. I don't care about it: I want information that should stay out of review.
The positive is that time saved on review can be spent on community building, helping in forum, discussing an actual review with audience etc.
