Let me start off by saying if you are currently watching "How I Met Your Mother" or are about to start it, don't read this because it will spoil the ending for you!
For anyone that has seen the show, I think we can all agree that the ending was not what you wanted, or at least not what you expected. Personally, I was shocked and disappointed.
Basically, "How I Met Your Mother" is about a man who is telling his kids the story of how he met their mother and practically every event that lead to it happening.
Right at the start of the show, the narrator, Ted, meets his soon-to-be best friend and the aunt of his children, Robin. They end up dating for a while then break up but always remain as close as ever. One of Ted's best friends, Barney, ends up dating Robin in later seasons and they end up getting married. At Robin and Barney's wedding, Ted meets his wife.
Throughout the last few episodes, you see clips of Ted and his wife's life together, until the final episode when it is revealed that the mother has actually been dead for six years at the time of Ted telling his children this story. When I found this out, I was shocked. It seemed very strange to have an entire show explaining how Ted met his wife only to find out that the wife had died.
In these last few episodes, we also learn that Robin and Barney had gotten a divorce. So, after Ted finally finishes his story, his children basically tell him that he told them the story of how he and aunt Robin fell in love and that he should go MARRY THEIR AUNT!!! WHAT? That to me is just beyond strange, how these kids would just be so okay with their dad marrying their aunt after he told the beautiful story of how he met their mother. It seems a bit messed up to me.
Overall, I really did love the show, but I definitely think that the ending could have been so much better.
