This is well made show and very entertaining. I watched all the episodes in just a few-days-spree. Sure, plot got some holes (starting from where Arisa is coming from in first place), some behaviors are schematic, some scenes make little sense, but the plot is fine overall, with some nice twists. Acting is good, camera is good, sound is good, F/X are good. futuristic vibe is there. I personally noticed a few opportunities for better twist or story development wasted and but overall I enjoyed this show. WARNING: there're are bloopers added to the credits, just after last episode is over. This ruins the whole episode's mood for me, so you may want to pause the playback after last scene.
Also please note that some reviews mention that you should choose native (russian) voice + subtitles. I am not Russian native, but I can speak the language and I definitely disagree. Beside from some odd translation issues that english version adds to this show, voices in English version are far superior and add significant value to the show. The tone of the voice, the sound - Russian Arisa is no that "robotic" as English one. So do not follow the review. Do not believe me blindly - just check for yourself first. IMHO watching the show in English is still better.
