Walked out of the cinema after sitting through 3 quarters of it (I guess).
What a piece of generic doody!
The whole movie is just setting a ridiculous premises (every word uttered is an explanation of these absurdities) and the 'underwater fysics' are annoyingly incoherent.
If you feel like wasting a few hours of your life watching dc pile clichés on top of more clichés go and watch, or save your money and just wait until the next marvel movie comes out for some actual superhero entertainment, I recommend the latter.
