I have never forgiven the show for having Lorelei break up with Luke and sleep with Christopher again, and then making us suffer through a whole damn last season of them not together. I mean, really.

Oh, lord, the finale basically gutted everything that Barney had done in the previous two seasons, it was character assassination- they needed to bring Ted and Robin together (because, as I recall, they had filmed the scenes with the kids years ago to keep them at the right age) and it's like they forgot about it…
