That's a horrible and unfair generalisation. It's nothing about wanting it to be darker or grittier, it's the fact that sacrificing Bruce Wayne is one of the only conceivable "non-open endings" to the paradox that is Batman and his war on crime. The other is retirement, which is also perfectly acceptable and not 'dark and gritty' at all for those of us that desire a finite ending.
