[THIS REVIEW CONTAINS SPOILERS] Enjoyable and intriguing, even kind of gripping, and I'm glad I watched it, but ultimately I found it a bit hard to buy into the central premise. Not the time travel per se, but the fact that a whole future society seems to have been created solely because one person felt unloved. How did he get so many other people to buy into his plan when it was all based on an issue personal to just himself? Or did I miss something?
Lots of aspects of the time travel weren't properly explained, as far as I could work out, even within the internal logic of the story - such as why did he have to go all the way back to the 1890s.
Still, I enjoyed it, and something not quite like anything else I've seen, which is good.
