Because this was horrible. This ignored everything that had happened between Ted and Robin, between Robin and Barney, between Ted and Barney and, especially, between Ted Evelyn Mosby and Tracy McConnell, all because once upon a time, this is what Bays and Thomas wanted to do.
They had plenty of opportunity over the years to course correct. They could have at some point accepted that the Robin/Barney coupling made Future Ted/Future Robin not only moot, but annoying. They could have introduced the Mother sooner and just made her a part of the gang — and every single moment this season in which Milioti was allowed to interact with the regulars (either in Farhampton or in the flashforwards) suggested that they could have pulled it off,
easily. Hell, even at this late hour, they could have recognized what they had in Milioti and accepted that that old bit of footage with Lyndsy Fonseca and David Henrie would remain unseen forever (or, at worst, be a special feature to lure people into buying the complete series box set), and that the fans would get over not seeing the kids react to the end of this endless story.
If "HIMYM" hadn't been as great as it was in its early days, or as great as it could even be from time to time more recently, I wouldn't care this much. I wouldn't be as angry as I am. But there kept being moments in this final season, and throughout this final episode, that reminded me of what the show is capable of, and it only filled me with more despair that we were clearly heading towards
the ending I feared was coming ever since "Vesuvius" aired. How, I wondered, could the same two men who wrote that great scene where Barney met his daughter for the first time be so tin-eared in this other area? How could the same writers who absolutely, 100%
nailed the moment when Ted and Tracy finally meet on the train platform not realize that they had already undermined it by spending so much of the finale on the dissolution of Robin's marriage and her leftover feelings for Ted? How could they not see the happy, satisfying ending that was staring them right in the face, and instead do...
this?
I can imagine Bays and Thomas back in 2005 or 2006 trying to figure a way out of the narrative straightjacket they created for themselves in the pilot, and maybe even doing a High Infinity upon coming up with this solution. I can even imagine that moment being so euphoric that it blinded them to a lot of what was happening on the show over the remaining 7 or 8 years. Back then, maybe it was a great plan. Back then, when I was talking to them at the press tour party, if one of them had asked me to turn off the tape recorder and promised me off the record that Ted and Robin would somehow end up together, I'd have been feeling some euphoria of my own. But stories change. Characters change. Shows change. And plans have to change to accommodate that.
This plan didn't. So instead of a bumpy final few years being redeemed by a finale that at least resulted in our hero winding up with a woman we all liked, and who seemed a perfect match for him, we have a finale that turns the title and narrative framework of the show into a case of Bays and Thomas following the letter of the law rather than the spirit. They and Future Ted promised us that we'd be getting the story of how Ted met the kids' mother, but all along she was just meant to be a distraction from the real story — like the kind of misdirection Barney uses in his magic tricks.
And the problem is that at a certain point the misdirection became vastly more entertaining than the illusion it was designed to facilitate, and as a result we just wind up feeling tricked, and annoyed, and wondering why we went along with all of it, when we should have known from the very first episode — from the Aunt Robin joke that got us into this gigantic mess — that this was a show that would not hesitate to make us feel tricked. And once upon a time, when we and "HIMYM" were younger, that was fun, but at a certain point, like the idea of Barney Stinson still having a Playbook in his 40s, it's just sad.
