I binged every single season over the span of four days. One thing, that got me really annoyed was four parralel story lines, working towards the same thing, not together. Same research being done four times, always from a different angle, this behavior repeated every season. The evolution of the story was definitely a love and hate thing at the same time. Same goes for the theme. Netflix has this weird behavior, where it does one theme, per season of the series. I have no idea who came up with that monothemaism, but it frankly gets boring, when you recognize the revelation from miles away. I'm sad actually, because this story did not hit me hard enough. Because the music was perfect, camera work - amazing, I love how they started out almost indie, with all the possible things practical in the first season, then slowly expanded. From the actors/extras, to the crew(s) and filming locations. The cast did amazing work, I've heard they wrote the actual script for this cast, not the other way around, like it's usually done. I appreciated it. Made everything fit so nicely. One letdown was that in season four, with that vfx budgets they spat out a ragdoll with a kinect 3d scan and basic maya od 3ds max simulation. Have no idea what happened there. Served such an essential part to the emotion of the story, yet the sucky vfx in these parts pulled me out of it completely. Let's talk episode length. Who on earth thought having the last season twice the runtime of the previous one would be of any good? Yes, they add separate side themes, each group's solving by themselves, but go way too much into detail somewhere, then completely omit some... Overall I was happy to kill my time with this series, but also sad because I wanted it to make me emotional. 3/5 and I'm waiting for the fifth season.
