Overall series is decent though not the great one out there.
There are some logical gaps for sure.
Series is about: (these are obvious and many understood in same way, just wanted to state here)
1. How few use the some supernatural phenomenon to their advantage and they eventually end up becoming more evil to maintain that image.
2. Another set of people involve in satisfying their whims using the same event. They are more dangerous from the very beginning.
3. If god created that Supernatural phenomenon , there might be some mistakes in the process. It would take time to rectify/modify them. GOD’S CREATION IS NOT PERFECT. IT EVOLVES OVER TIME.
4. The CGI MONSTERS are just using the brute force and they do not have the ability to care about consequences. Those visuals were unnecessary, horror can be created with simple creatures as well.
5. How humans try to give meaning to any event though it’s never clear why few were selected for that hell.

Few unanswered questions for season 2
1. What is the selection criteria.
2. How did baby survive
3. Why that dead lady became human again .
4. What is the intended message for that supernatural phenomenon or is it just random or is it done by some demons.
