You're not good, and you're not bad." This is one of the lines that pops up repeatedly during loading screens in Need for Speed Undercover. It's a phrase designed to flatly establish the coolly antiheroic nature of your role as a street-racing undercover cop, though there's no such grey area when it comes to the actual quality of Undercover. After last year's Need for Speed: ProStreet, an oddly street-less street-racer, I saw some good potential in Need for Speed's return to the heady blend of cops-n-robbers gameplay and goofy live-action cutscenes that made Most Wanted such intense and intensely silly fun. But execution is nine-tenths of the law, and Undercover feels careless and mercenary, lacking the enthusiastic verve that made Most Wanted more than the sum of its parts.
