I've seen that comment copy-pasted a couple of times now.
Contrivance and excuses are all that is, I'd have to say I'm still not impressed. If anything, the 4chan comments that Windigo linked being actual canon would be the only way to really change my mind about him.
We're supposed to be in awe of his "presence"? Yeah, I do have the "gall" to question that. Evil for evil's sake is rarely done well, and you know why so many people are unenthusiastic about that? It's just too dang easy. Anyone could write up a big bad snarling evil king who wants to enslave everyone and do bad things, because reasons.
I made this argument over at EqD as well. For the sake of comparison, who is defined as one of the most pristine examples of a good villain ever devised? This guy:
He did it all man, he blew up planets, killed Obi-Wan, strangled his own officers, betrayed just about every friend he ever had, dropped the father bomb on Luke, then had a radical reversal at the end. He had dialogue, he had interaction, he had motives, it was all there. Take all that away, and craft a villain that's nothing more than a "powerful force" who harms people, and what are you left with?
This guy:
You tell me; which foe is more fun to watch?
Now, Sombra may be slightly more interesting than the blob, but that's only because of everything else happening in the story. He did barely anything personally.
I do have a theory about why they did it that way though; if he is truly dead, then they would have a problem on their hands if they gave him too much personality. It's the storm trooper mentality; the less human they seem, the less you care when they die, and you know how much western television hates giving too many feels to their young audience.
And as for all these comparisons to Sauron, I don't buy it. Sauron had a vast amount of history available to anyone with the inclination to find out about him and his interactions with Middle Earth, whereas with Sombra, we're left guessing as to who this guy is and what he wants. Now, if he does get more development as the series progresses, great, but as it stands now, he was far less entertaining than the other three major villains.
You know what the sad thing is? We keep going back and forth on the topic of what I believe was the weak point of the story, while ignoring many other interesting things about the episodes. Did anyone notice the similarities between this and the story of Hearth's Warming, for example? Think about it.
