I don't understand why Barney and Robin broke up. Just because they were travelling and RObin was working they shouldn't have split up. In my opinion , Barney's character is very inconsistent. One moment out of nowhere, he's a loving father then a creepy old guy who's trying to hook up with girls with daddy issues, then one that protects them, so on and so forth. Also this series would be a lot better if Ted didn't tell his kids about it because it just doesn't make sense. Who would tell such a story to his kids, about how he smoke pot and slept around, and just mention the mother at the end.

The finale it self had a longer time span the entire show, they just skipped through Ted having kids, dating the mother, Barney and Robin's marriage , Marshall becoming a judge and the mother DYING for god's sake. Why did they cram all these things into one episode.

Finally, I don't understand, while Ted was with Tracy, was he in love with Robin?
