I am not being fair for dropping this before watching the entire series so my review may not hold water.
my POV: if there is no distinction between human and AI, what made the protagonist accept this AI when he is a recluse and introvert? The set setting is not matching the concept. AI is supposed to be aiding emotionally but so far, what I have seen was the AI being a physical help. The AI doesn't seem to be set with boundaries and has overflowing emotions - more than the human. The concept hooked me but lost me when I didn't see the execution matching the idea. I might have a preconceived notion of an AI that is clouding my judgment, so I may not be being fair.
