Unfortunately as is common with movies featuring multiple leads, there doesn't seem to be a good balance for any one character, and even given the movie's two and a half hours run time, I didn't feel like we got to know any of the characters very well, let alone their chemistry with one another.
While the dialog had no real stand out lines outside of the semi-cheesy trailer lines, they did a good job avoiding typical comic-book sounding lines. For such a big budget film, it had very uneven effects; props, rubble looked decidedly cheap, and explosions were occasionally just sparks. In addition, the dream sequences were unnecessarily long and silly, breaking the immersion and failing to impart much sense of purpose for the plot.
As much as merchandising would have you think, Aquaman had no real part in this movie, and the final fight featuring Doomsday felt like a cop out for a truly high stakes egg status. Ultimately, this movie simply doesn't serve much of a purpose other than tie up the fallout from Man of Steel. Hopefully this is just growing pains for the DC Expanded Universe than an actual indication for the future of the franchise.
