Ten years ago, How I Met Your Mother came to an end with season 9, and Ted's (Josh Radnor) story to his children about how he met his wife, Tracy (Cristin Milioti), finally wrapped up. The hit sitcom famously had a controversial ending that rocked audiences worldwide, with many voicing their disappointment of how its characters' storylines were finished.

However, there were more issues with the finale of How I Met Your Mother, other than Tracy's death.
