There is zero sense of escalation or dread too. It's as if the creators of the show received a note saying "Make sure a lot of supernatural stuff happens in the first few episodes! I want ghosts! I want magic! More ghosts! More magic!"
Made worse that by now the crew should know that if there's a story about an evil curse or monster it's best not to mess around with it because it's probably true.
By the end of the second episode there are flying soul monsters throwing the ship around, people making fire with their hands, evil ghost doll trees, magic dragonflies, possession, people being sucked into the the nether world and popping out of grave portals ..."
They could have teased out some of this stuff to build up to something. The door on the ship could have been closed until the second episode. The soul trap could have been harder to release. They could have spent longer finding the videos showing the magic rituals of the missing doctor so the supernatural overtones were more carefully dripped into the story etc.
It's like the show is so afraid of falling into the same trap as Lost by never answering questions in prompt fashion and being vague about their intentions, that they are determined to make sure the audience is punched in the face with a supernatural ghost monster being every week.
