My problem with the DCEU -- other than the fact that they chose that acronym and not the far more symmetrically pleasing "DCCU" -- is just that it's such a sharp tonal shift from what made DC Comics. They were always the brighter, more colorful, more optimistic of the two. Now, to carve out a unique identity, they've adopted the Snyder/Nolan-esque drab and dreary style where every shot has to be run through a blue filter. It's just hard to swallow. Like the first time you try dark chocolate as a kid. Rather than creamy goodness, it's just bitter.
Honestly, if they lightened things up a bit -- literally -- I would probably be more amenable to the story decisions.
