Great quality is all that matters, as a fan, which is why DC should release the Snyder Cut for Justice League...
We, as fans, shouldn't be able to care less about the $$$$$ studios make. Comic book movies shouldn't be geared to general audiences. I don't care if Karen doesn't know who Vulko is - us comic book readers would - and he should've been in Justice League.
Stay true to source material (not completely, as we do need changes and surprises to stay interested) and stop pandering to critics and know-nothings, film studios.
Yes, they need to make money and yes, they need to entice general audiences. Look at what the MCU has accomplished, though. People know who Iron Man and The Avengers are because of good-to-great quality movies that started a foundation where the casual moviegoers are actually interested in the properties despite not being original comic readers.
Marketing and high-quality films will draw crowds.
