I think the main thing I want is someone who can be fair.
Especially with Japanese games, I've noticed a good many reviewers come in with a "fuck is this garbage?" mindset before they've even pressed the start/touchpad button. That serves no one. Nor does blinding fanboyism, which is a huge problem among "professional" reviews. Personally, if someone feels they're incapable of giving a game/series a fair shake either way, they need to recuse themselves from that particular game/series. Seriously, Jeff should never even look at a Musou game again if he's going to be so cynical all the time about it.
