If you like IT stories

The story seems pretty solid with some not of the time things. The real story begins around 2012 and they were using windows XP?. The their phones, Chinese brand, had apps already?, not just the ordinary from the year, but they created a medical app for the phones if that time. It's a TV show, I get it, but still too many things didn't go with the years. Then there are some lose ends at the end that you will find out yourselves if you pay close attention.One bothers me the most. Anyways the end was ok, could of been better but everyone got what they deserved.
