Okey dokey, so you've edited your post, and it makes more sense now.

You're in essence right to wish for well-informed reviews (which you label 'objective', but that's still a misapplication of the term). But you're also being unreasonable. Like I said, most online anime reviewers are YOUNG, UNPAID, CASUAL writers who don't have the time or inclination to gain years of education and understanding about this artform. It's just not feasible. It doesn't mean that online reviews are useless either. Indeed, there's a lot of junk, but a mediocre review can still give you a sufficient taste of what the anime is about.

Finally, even the paid professionals, no matter how educated, only give you their opinion. Their reviews are likely to have fewer errors or misconceptions, but just because they know who wrote the script and how long the composer's been in the industry it doesn't mean they can give a truly objective view. Whatever review you read, you are absorbing someone's preferences.
