Robin Scherbatsky is a beautiful, intelligent, accomplished woman. However, for 14 years she apparently has not been able to have a successful relationship with a man who supports her career and isn’t interested in having kids and would love to travel the world with her. No, apparently Robin is like Mary in It’s a Wonderful Life if she had never met George Bailey—the lonely spinster who would have spent her life in the library.
I stopped watching the show after Barney’s proposal. I was so angry that the writers gave the message that it was okay that Barney had spent months manipulating Robin, with a deliberate intent to hurt her, because OMG HE PROPOSED! IT’S SO ROMANTIC!
So sadly, I’m not completely surprised that, in the end, the writers threw out any characterization of Robin as an independent woman who knew what she wanted from and in her life and went back to the idea that she’s just a prop for the male character’s development (Ted/Barney), and his trophy for the end of their particular journey.
