Had the show not had an 9th season, I think the finale would've been MUCH more fitting. But for the past year we've focused primarily on Barney's evolution and the wedding, which was thrown away 15 minutes into the finale. We've meet and become fans of the mother, who was thrown away with a passing mention about her sickness. Which I guess would be accurate IRL (a passing mention of an illness 6 years after-the-fact), but television isn't real life and the audience didn't know anything about it. The audience (by and large) came to terms with the fact that Ted and Robin would never be together since they haven't been for the past, what...three seasons? There was a general acceptance of Barnbin and - since it's a sitcom - everyone is assumed to live happily ever after. Again, not realistic...but its generally the way comedy works. No divorce. No death of the title character and if there is it's not a friggin' afterthought. I think the show was written for 8 seasons. The CBS wanted another and the writers had to pad 24 more episodes.
