It's all right. It tries to be complex, but really, it's just a lot of exposition and plot twists. There aren't really any subliminal messages or deep meaning besides that it's better to die doing something wicked rather than dying like a loser. Not even kidding. That's just about it. Besides that, it's mostly just "Name That Sci-Fi Movie!". (SPOILER ALERT, SPOILERS AHEAD)
Here's some examples: A.I. fighting against a secret society that wears black leather and sunglasses and is led by a famous African American actor who's the coolest one there is The Matrix, giant thing in space that holds people who will soon travel to another planet far off (well, moon in this case) is Dune, destroyed New York that is turned into a beach like area is Planet of the Apes, and so many more.
Basically, it's good enough, but in my opinion, not quite as good as the director's previous work on Tron: Legacy, which at least was original in design.
Oh, yeah, and there's a naked lady who is shown in shadow and then lit up in a pool, but from a distance and in the waves when closer. But it's like, THAT CLOSE to full nudity. As far as violence goes, little blood, LOTS of explosions. Like, a Michael Bay level of explosion-y non-bloody violence.
BTW, not to be spoiler-y, but lots of creepy clone-embyro things in an evil thing's base.
