some of the things I don't really get like how Olivia had a different childhood etc.
Keep in mind that young Olivia met young Peter, and he is the one that brought her back to Walter. It is quite possible that after young Olivia ran away she didn't come back in this timeline (and was taken in by Nina).
I still hate the lazy writing with turning the lights on/off. It just bugs me that they have such a glaring oversight.
The events of the first three seasons only happened to Peter, and Olivia remembers those events so they may as well have happened to her.
I still really liked season 4 despite some unevenness.
