Review of The Devil's Hour

This series does a good job of building up the mystery and keeping you wondering what exactly is going on. However, once I finished the final episode and "the big secret" was finally revealed, I realized that there were still too many things that didn't quite make sense. For example, at the end, it shows the neighbor family (with the little girl) being burned by a fire in what had been Lucy's house in a different life and in a timeline where Isaac had never existed because Lucy had never had him. But it was Isaac who had started the fire, so why would this other family have also experienced a fire in a life where Isaac doesn't even exist in order to start a fire in that house? Who started that fire? It just doesn't make sense. Secondly, if everyone's lives "loop" as the man at the end states, then why doesn't everyone experience "deja vu" as strongly as Lucy does, or in other words, why doesn't everyone have flashbacks of their other lives like she does? The police guy certainly doesn't, and nor did his partner. So why did Lucy have them so strongly? Again, this film does a good job of building up the mystery and keeping you waiting for the resolve, but it still leaves too much that doesn't really make sense, in the end.
