I binged the entire four seasons in under a month. All of the characters are so interesting - you love and hate all of them at one point or another. It's an emotional rollercoaster - I cried A LOT! I love how each episode has its own story, but there is always a thread of flashbacks or flashforewards that keep you hooked until the end of each season. This is not a series you can just have on in the background - you really need to be giving it your full attention to appreciate its brilliance. Couldn't recommend it enough!
