I don't find AHOV pretentious either, I didn't say I did. I said that I find TDR to be a vastly superior film to a film which is very good.
As for TDR, there are great character archs for Wydell and for the Fireflys where he gets progressively worse because he's so totally consumed by revenge that his judgment is clouded beyond reason, and they get progressively better. Rob shows them as the most heartless, abhorent pieces of **** possible during the early portion of the film, then has them endure the same torture and degredation that they had been dishing out all this time, and it's only then they come to understand the wrong that they had done before they died.
That was my take on the ending, what the Fireflys were thinking before they died is left up to the viewer. Both Wydell and the Fireflys end up with qualities that could be interpreted as positive or negative. The film also carries a great message that murder is murder, whether you're committing it in the name of God, or in the name of the Devil makes it no better.
The Devil's Rejects is one of my favorite films of all time, I find it very deep, and very entertaining with many different layers to it. I also love how Rob completely switched around the common genre pattern of having the villains start off dark and menacing, then having them become lighter and/or funnier as the series progresses. He did the opposite with Corpses and Rejects.
As for that "you have to be kidding, you committed a sin saying that!" That's precisely what I'm talking about, that's an extremely pretentious attitude. Film quality is subjective, those that aren't pretentious don't come off with the typical holier than though attitude when debating with those that feel differently.
