Im a grown man and don't cry for anything, never once watching any tv shows or movies have i got emotional until i watched the first season of the OA. It was specifically the end of episode 5 and the last episode, i was a mumbling mess.
Ive watched the two seasons 4 times now, never gets boring. In my opinion one of the best shows to have ever hit netflix.
If your open to another dimension and spiritual stuff this is a must see. It will leave you begging for the storyline to be real.
At the end of the second season you will be searching for the third season release date and be hugely disappointed to discover its not going to be made.
Thats the sign of a great show.
