Seriously, Ted giving the locket to Barney and then calmly refusing Robin's pleas to run away with her were two of the series' biggest highlights, IMO. He wasn't just barely hanging on and saying no because it was the right thing to do; he truly didn't have those feelings for her anymore. To basically throw that great, pivotal moment by the wayside is nothing more than a cop-out.
This x1000. And to throw all of that character development out in a 10 minute montage that covers 20 years (nice pacing) is terrible.
