I actually liked this movie very, very much. It is a bit slow in the beginning, but once the mystery is out, the tension is tanguable and keeps you at edge. Not a tension in the way of fast action, but an underlying tension, a real life or bigger-than-life problem that is there and has to be dealt with, and the viewer gets sucked into it.
The acting is very good, plus the characters are likeable, almost innocent in away, and bright, and real. The chemistry between the two main actoers is also an almost innocent one, a careful one, but still strong one.
It has some elemnts of other mystery movies that I liked ver ymuch, I am actually a fan of "time travel" and "time loop" movies, I like the sheer mystery and bigger-than-life feeling of them.
And even though the sci fi element in this one might not be so much out in the open, it remains a msyterious, eery topic in the background. The way it is explained with the flood, is really good!
Actually it is mostly a mytery movie, with elements of drama.
Really good!
