Shekinah Glory Cabuan

I finished the 4 seasons and I'm impressed and so disappointed at the same time. There's a potential. I can see how the writer understands the work of evil on different forms/ways and how psychology and science explain some. But there were cases and scenes that are left unsolved. I thought they'll get back on those cases and solve it on the next episodes. But no. If you've watched it you'll know what are those scenes/mysteries that I'm talking about. An example is when Kristen saw the pregnant wife of David's father giving birth to an evil. She didn't even tell that to David. Another one is the acid that went down from Kristen bedroom to the basement. What's the meaning of that? And many more... Just disappointing.
