Leaving aside the series finale that has long been in the running for "worst ending ever" (and believe me, we will get there...) the first time that you watch How I Met Your Mother, it's sometimes difficult to pick out why you feel how you do about certain characters.
Everyone agrees (or should) that Marshall is a stand-up guy and all round decent person, but there are flaws and shortcomings in everyone's character and conduct over the nine seasons that the series ran for. Sometimes it's a major plot point and you have no choice but to notice this bad behaviour, but other times it takes a re-watch to really plumb the depths of how terribly some of these people acted to others.
One of the worst culprits is arguably Robin. Implied to be the eponymous Mother throughout the early series, once it was revealed that she was "Aunt Robin" most fans gave up on the idea and viewed her through the lens of being just Ted's friend.
And boy does she fall short of the mark on multiple occasions. Here are just ten.
