What? Dolores is completely unreliable we don't even know if she perceives time normally at all. Thandie is shaky too - she MIGHT be straight, but she's limited by what her programmed background is even after piecing together things from her deaths.I disagree with this. There is only ONE unreliable narrator which is Bernard, and it was easily shown as to why he's unreliable because his memory is fracture due to shooting himself in the head in season one. And because of his fractured memory is why we got the non-linear timeline, because the majority is coming from his perspective where he is living or revisiting parts of everything that happened. I see that is almost genius in how they did it because it wasn't forced jumps just to have it, but rather fractured perspectives from a fractured mind trying to piece the puzzles together. So everything slowly gets revealed as he slowly learns more as to what happened from the night of the massacre to present date.
And all the other side storylines are straight forward. So, I believe the writing is just fine.
