Well Kidray, since you are the only one who responded in an intelligent manner, I'll reply to you.
You're completely right about the subjectivity of art. However, since this site is a democracy, one person can think that a submission in the top 50 is crap, but it does not make it a crappy submission. On the other hand, if everyone thinks a submission is crap, and one person thinks it is great, it doesn't make it a great submission.
It's a sad truth about art that is directly reflected in the "ratings" system of both this site and any other reviewing medium.
You, unlike most of the other tickle-toes in this thread, are thinking in the right direction, and I completely understand why the guidelines exist as is; all I am saying is that if the author clearly put no work into the submission -- and the score will typically reflect that -- why should a reviewer be expected to put any work into their review? I know it's not an argument of reason, for the reasonable thing would be to give the piece a zero and move on, but 0s get submissions deleted, reviews like the one I included in the original post do not. They do convey a message to the author -- as much or more than a 0 does. To me it says, "You didn't do enough work. If you want to litter the site with garbage, expect people to respond in kind."
I know that the rules will likely not change because uniformed rules are much easier to enforce and make for less grey-area decisions. I suppose I was really just venting. Still, I have always viewed Newgrounds (having lurked here from the start) as more of a midnight cult-movie screening, a la Ed Wood, than a serious and formal medium for professional artists; in fact, that is what I love about it so much.
I just hope the trend towards "professionalization" doesn't continue, because although there are some fantastic artists and game designers on this site, the vast majority are not.
P.S.
To the rest of you starry-eyed kiddies...
The real world is far harder than you may think. If a mediocre artist gets on here and all he hears is "Uh mah Gud! Arrsum! Dis 1z s000 k3wl!" he may not be motivated to improve. Bad or negative reviews can be just as valuable as a good review -- especially since 90% of good reviews don't say anything constructive at all and simply amount to, "it was great."
I'm also not saying that they don't need to hear good reviews, as that is an essential part of motivation as well. But your arguments against "bad" reviews are misguided. The fact that they "are the rules" is what this post brings into contention. And just because a person creates something does not in any way preclude another from responding as they please. In reality, you can and should be able to say whatever you please about someone else's work. In other words, just because I say I like apples doesn't mean you need to give me one -- that is your choice.
I am very rarely derisive in a pointed fashion. I normally choose to be rather lighthearted in my negative reviews because they are easier to shrug off. I can write at least half the people on this site a very convincing essay (whether true or not) that states why they will never be a successful artist, but I never even hint at that.
In short, I'm on here for the same reason as most people: to enjoy myself. And I'm not going to let an artist decide whether I get to do that or not. If the submission is good, I will enjoy it; if it is bad, I will enjoy it anyway. It's the same concept behind watching B-movies or throwing pickles and popcorn at a howler of a film.
I love NG, so I am all in favor of keeping it how it is -- and even restoring it to how it was.
Thanks for reading; sorry about the length.
