The problem is simple... the writing. From the start the writers didn't know how to introduce the character's properly. They didn't give the viewers an opportunity to get to know them, not even on the most minuscule level, before skipping to another character to introduce them.

And the problem continues onward as it moves too fast from one scene to the other, delivering the story in clips that don't allow the audience to become acquainted with anything and leaving them with a "meh, I really don't care" feeling.

The art team was able to set the mood. The actors did their best with what they had.

But the writing and direction killed it.
