This is a rare case of me wanting so much to like something and getting mad on how bad it is.

The final plot twist was great, I didn't see it coming. The only clue I saw was the repeated times that Stem didn't care to kill ppl, that raised a flag on me. But the movie kept rememering of K-9000 so I was biased to believe they'd end up becoming a team and work together.

Anyway, I have to record the list of the issues that annoyed me and spoil the movie

• car being hacked: I see no reason for any car company to let a car be accessible remotely
• chip to link spine cord: on, it was all faked on, but still, with tech to make all those implants it would be possible to relink the spine cord and save Grey leading the chip discardable
• weapon implant on arm: cmon ffs! they should be able to think on something better to showcase body implants!
• pierce eye to get access to record: if they're able to implant camera on eye, they surely would make a better way to connect to it
• shutdown command: that made me so much annoyed! idk what's worse, to have Lix kernel on the chip and Stem running above it or the system taking so long to shut
• partial control of the body: either Stem has control or the body or not, it's not possible for the body to move partially like that when Stem was being shut down
• Eron shutting down Stem: if it was Stem's order to be placed on a chip and implanted on a human body, Eron either would be able to betray it and shut it down or not disable its abilities at all
• Stem needing for Grey to grant it control of the body while Eron is unable to control it, yeah I know it's explained later, will create another thread about it
• Grey be able to control the body and stop Stem from killing the cop
• I'm almost sure that from spine cord Stem wouldn't have access to ears signal, surely he'd not have access to eyes's

The worst issue of all: Stem becoming able to control the mouth and lock Grey's mind. Cmon that's so dumb! I even thought it'd be revealed that the chip was able to move and get to the brain! The movie even makes explicit that Stem was unable to access his thoughts and he needed to speak to talk to Steam!

What a mental breakdown would cause would be Gray to faint and we have a body moving with a fainted head, or at maximum lead Gray to become schizophrenic and have hallucinations. From the spine cord Stem could send to Gray's brain fake tactile signals, but he'd be unable to control head's senses.

And, if Steam's objective was to take full control of the body, why not have the chip implanted directly on the brain to begin with?!
