I wasn't able to get that to play, but if its the video I'm thinking of, that's not Nile. It's Iniquity. Nile is even more brutal.
But to return to the question at hand, you have to realize that A) music is subjective. Anything that is a sequence of sounds in an organized fashion is music, whether you like it or not. I could record generic everyday sounds and arrange them in some fashion, with or without a noticeable melody, and it would be music. And B), just because you don't like something doesn't mean it doesn't take talent or skill. Growling well is extraordinarily difficult. Yes, its "easy" to scream at the top of your lungs. Some vocalists do this, and they annoy the piss out of me.
Opeth has been mentioned quite a bit in this thread because they are one of the most ridiculously talented bands to have ever formed (in my unbiased, objective view

) and care about melody and music. Mikael Akerfeldt has worked for years to perfect his growl, and intersperses it with clean, mellow vocals (same goes for the instrumental aspect of their music). Whether or not you enjoy their music, if you know anything about it, you can recognize their talent.
Furthermore, metal is all about aggression. Not necessarily anger, hatred, evil or Satan, but aggression. It is high-energy, aggressive music. The guitars are distorted, the drums are hard, it only makes sense for the vocals to progress to distortion as well. You can only sound so "metal" singing normally. Think about it, in Opeth's song "Serenity Painted Death," Mikael sings the following lines:
"Each and every one would die at my hand
Choking in warm ponds of blood
At last, weak and torn, I went down
Drained from strength, flickering breath"
Whether you think those are great lyrics or not, and regardless of what you think of the song, or the band, or the genre, those lyrics would not have the same effect if they were sung in a clean style. It's meant to symbolize the more intense emotions, and clean vocals just can't do that. Same thing as using distorted guitars. Can you imagine trying to play metal with acoustic guitars and John Mayer's voice all the time?
I can completely understand why most people don't like growling. It's tough to decipher the lyrics, it sounds alien or demonic and yes, it has a tendency to sound like a belch. I think it sounds awesome because it's so brutal and alien sounding. It unleashes the intensity that other styles just cant match. Also, metal is much more riff-oriented than vocals-oriented. Most metalheads care first and foremost about the music, and growled vocals are just another layer of instrumentation in the songs. that's not to say that the lyrics are meaningless, just that in the grand scheme of things, how things sound tend to be heard first.
I guess I've written enough about such a silly little topic, but I just wanted to inject my two cents to the conversation. Bottom line: yes, some death growls are ridiculous, and yes, a lot of death metal bands suck (Cannibal Corpse being a prime example). A lot of bands sound the same to an outside observer, but honestly, that is true of any genre. All country sounds the same. All jazz, classical, blues, rock, klezmer, Gregorian chant, etc. It all sounds the same until you embrace the subtleties and nuances that separate bands, styles and songs. Growling is hard to do correctly and does not necessarily cover up a lack of ability in regards to singing or songwriting. And, as amazing as it may sound, some people actually enjoy the way it sounds.
