I kinda noticed how Barney and Robin just became meaner this season. I dunno, I'm not too excited by the wedding now that it takes 35 years for it to happen.
I'm not sure they're meaner, but I think the show is having trouble communicate their rightness with originality, especially since every episode is the same theme repeated.
(Plus it's a late season in a show, and as a tendency, esp with sitcoms, a lot of writers end up writing the parody or the easier bits of a character, because these characters have already grown. If they were to grow anymore, the show risks losing its audience, therefore: keep them the same, the same, more of the same: and they become 2D versions of people.)
