Most of the side stories are boring,
But i quite enjoyed the part of the two ladies who dropped in current time from past and shocked and surprises they encounter and their reactions.
As everyone stated the climax is kinda felt unsatisfactory considering how they ended the Mother ni law part.
Anyways , skipping the boring parts and watching the one that engaged me , i would say i am glad i watched this despite the ratings the plot intrigued me and it delivered what it promised.
