I for one loved and enjoyed the finale although I was sad at the end cuz the show finally came to an end. Throughout the show, I was never a fan of Lily because I always thought she was selfish for good reasons most of the time.
Alyson Hannigan did a great job because she always wanted the crew to stick together. Her tears during the finale had me going as well. Everyone's tears had me going because not only were those strong moments, but also life changing moments for all of the crew.
** CAUTION MAJOR SPOILER ALERT ** ** CAUTION MAJOR SPOILER ALERT **
I didn't mind the mother and Robin ending at all.
Most of you were #$%$ by the ending, but this is how I see it
-Ted met the mom, whole point of the show, he loved her with all his heart, was finally able to let Robin go. He did, which is why he married and had 2 kids with her. And Tracy was perfect for Ted, remembering what Stella and Victoria said about marrying and inviting ex's all related to Robin. Tracy LET Robin attend and she did. That shows that Ted found the right woman that let him still be friends with Robin while Robin finally realizes that she wasn't enough to make Barney change.
-Barney has always loved the single life, always had and always will UNTIL he got a kid, that one on one scene between him and his newborn daughter was nothing but a strong moment for Barney, probably the strongest moment through his 9 seasons.
-Marshall was meh, he was always a consistent character, always selfless and always thinking about other people. That's why he was my favorite character throughout the show.
-Robin, also another consistent character, she always put work in front of everything else but was always wishy washy with the relationship thing.
Finally Ted, his kids were right, although the series was labeled "HIMYM", majority of the story always revolves around him and his love for Robin. He did let her go during the wedding and up to the point where the mother passed away.
And last but not least, most important scene to me of the whole show was the ending. The ending ended where it all began. Ted and the blue french horn. He began the story for his love for Robin with the blue french horn and ended the whole story with the blue french horn. It was a great ending in my opinion.
