Yet again, another series finale can't live up to expectations. The end of How I Met Your Mother was a ghastly abomination that soured the entire show.
In case you missed it, here's a recap which is funny since the entire episode was in itself a recap. Barney and Robin get married. Ted meets the future mother of his kids, Tracy. A couple years later Barney and Robin get divorced (if you were surprised or upset by that, you're unrealistic bordering on insane). Ted and Tracy have their first kid, Lily and Marshall have another one. This whole time Robin is becoming more isolated from the group til she basically never sees them. Ted and Tracy continue to postpone their wedding for years despite having another kid. Barney knocks up a random hookup (despite years of bedding hundreds of women and it never happening before, guess his marriage to Robin made him forget how birth control works). He has a daughter with a woman who evidently has no name and we never see.
Then, in a move that pisses on the concept of the entire series, Ted's wife dies off screen of an illness that is never named when their kids are still really young. So, 6 years after her passing is when he's telling his teenage kids the story. Then his kids tell him it's okay to move on and go be with Robin for whom he's still carrying a torch. The end.
So the finale basically the finale takes a giant dump on the entire concept of the show. Not only does it make Ted's relationship with the mother of his children nothing more than a brief detour from him yet again going after the most emotionally unavailable woman that's ever existed, who has rejected him numerous times, up to and including dating and marrying his close friend who is a lying sociaopath, who probably has ruined lives (you're gonna tell me not one of those girls he fooled into sleeping with him got depressed and killed themselves, developed a drug habit, or simply never trusted anyone ever again?) and almost certainly has had more than one std. It also makes Ted a terrible father who, instead of telling his children actual stories about their biological mother who they only knew for a few years, he continues talking about the exploits of his selfish ex girlfriend whom he's loved longer than he even knew their mother. A huge problem considering the title of the show and it's build toward that moment being so significant the show was based around it.
One big problem that separates this from say the crap ending of Lost, is that they're already casting for a spinoff called "How I Met Your Dad". After seeing HIMYM end in such and disappointing and stupid manner, do they really think anyone is going to tune into that show knowing what kind of a resolution they can expect? I know I certainly won't be watching.
