I think The River Dragon is a fucking awesome song. I also think that what one person may feel about one song doesn't necessarily mean it's factual, but the opposing opinion doesn't either. The River Dragon solo isn't the most technical of all solos, but if someone feels that's the greatest solo of all time, then that's his or her opinion.
I personally think Time by Pink Floyd is the greatest solo of all time, but if you ask all the guitar dorks who think that just because a song has shredding it makes it a better song, they'd probably disagree and call you all kinds of names. It's all a matter of opinion.
I personally think that Yngwie Malmsteen is boring as hell, no matter how fast and technical he may be. I'll take Nuno Bettencourt over Yngwie any day of the week.
If someone thinks a band is flawless, then IN THEIR OPINION, they are flawless. Let's not crucify people for their personal taste.
