This post will have spoilers.. so.. you probably shouldn't be in this thread in the first place if you don't want to get spoiled:
Barney/Robin
I loved them together, I always thought they were the best match.. I wonder if they would have worked out if it wasn't for Robin's job
I hated that Robin wasn't even in their lives for so long
The mother
I wish they made it sadder... he mentioned her being sick, and then the kids mentioned that she's been dead for 6 years. I wish we saw a funeral or something, what happened in those 6 years?!
I saw Robin/Ted coming right after the divorce, given the previous clues that the mother would die. I never thought they would work because they wanted different things, but I guess it works out perfectly at this age with them already having what they wanted in life (Ted had a family, Robin her career).
It did seem now that the whole story was "How I Met Robin", the kids have a point. Otherwise I think the story could have started at the Irish pub with the yellow umbrella. Kind of fell bad for the mother once again.
