All of it so much. NE had enough chemistry and enough of an amazing story to pull it off, but the writers kept screwing them over for shocking effect during the whole S4 and then they fixed literally nothing with Naomi's cheesy speach and "I loved you since 12" nonsense.
Freddie/Effy, in my opinion, where the only couple that deserved a happy ending. This two went through so much, never cheated on each other, loved each other so strongly and they deserved to get at least a decent resolution. The kind of exit Freddie got was ridicullous and horrible and disrespectfull. I am glad that at least their relationship in general still wasn't ruined, because the last thing Effy told Freddie was ILY and it was obvious that he was the only one for her and she chose him in every single possible way over Cook and over anyone else, but then again, it does not take away the awfullness of psycho doctor SL.
