Several episodes seem to lack luster at the beginning. I began with an expectation of supernatural involvement, and was constantly irritated at the slow development.
But, the relationships between husband and wife, the mysteries, and the emotional turmoil kept me in it. I am not easily surprised, yet this did exactly that. The end is well worth the wait. You can argue that it's unbelievable, but I don't think that comes into it. It's explanatory and dramatic. You will be hard-paced to find any single season drama that resolves so well.
The key to any resolution is that it meets some criteria:
1) It is not fantastical. It could happen without violating physical laws.
2) It has a certain bitter-sweetness. Not a requirement, but definitely helps.
3) It resolves the crisis of the main character.
4) It lets us love the character, after having had her character impuned upon throughout. It redeems her believably.
Give it a try. Relax.
