At it's base it's not a terrible movie, the problem is that the base consists of so many ideas and subjects that it's hard not to get lost in all of the mess.
It's a critique of technological advance, AI, privacy & spyware, (experimental) surgeries and health, the Chinese, capitalism, rich people, modern society and so on and so on ...
The bad writing doesn't help either, the dialogue can be stupid or just straight up exposition, the story jumps between characters and plot lines in a sloppy way, and I know (or at least think) that some of the dialogue is self aware and doesn't take itself seriously, which made it corny, funny (the audience laughed from time to time) and honestly fun. You can consider this movie a "so bad it's good" movie, at least that's how I see it, I certainly didn't suffer.
