I absolutely love Serial Experiments Lain! The way it plays with reality and identity is just mind-blowing. The series constantly tricks you into questioning what is real and what is just a construct of technology. The blending of the digital world with the physical world is so well done, it really makes you think about the nature of existence. The unreliable narrator adds another layer of trickery, keeping you on your toes throughout the whole series. It’s a masterpiece of psychological and philosophical storytelling that never fails to leave me in awe.
