I really thought I had it figured out before the end. I thought there was a twist to explain something that never got told. For instance, how did Lennon's body not decompose after an entire year of being dead? I kept thinking this would get explained because there's no way any show would actually have her float up dead and look like she's been dead for hours, not a year. Plus the water and animals in the ocean would have accelerated this. I'm so mad they didn't even try and explain that.
