I voted adequate, but that's mainly because I think it will end up like Suicide Squad or Man of Steel: people will argue that it's flaws aren't flaws, but genius writing, and others will only be able to see the flaws.
Now, both of those are bad movies (and no, there is no "genius" to any of the DCCU movies so far), but they are passable for what they are; misguided attempts at redesigning characters with no real interest in what makes the characters interesting in concept.
My theory is that this will be Avengers with more slow-mo fight scenes, and no small amount of retconning.
Now, with Geoff Johns taking the Feige role at DC, I have high hopes that the movies will at least improve from here.

There's also no genius in Marvel movies, but they do give off a sense that they respect the concepts of the characters for the most part so far.
