It starts of great but the pacing is very slow and as you progress through, the show creates more and more questions and leave them all unanswered. I understands this is just the first episode but it should've at least solved some of the mysteries by the end but it just leaves you with million questions.

Also the character introduction was terrible but I guess it got buried under the "mysterious" aspect of the story.

I think they should've focused on the introduction, there was no need to put these many questions in a desperate measure to attach the audience to the show so that they watch future episodes.

Overall, not bad, it's promising but they're walking on a thin blade.
