Fans Are Not Happy With The 'How I Met Your Mother' Series Finale

Warning: Major spoilers if you have not watched the finale.

The series finale to "How I Met Your Mother" aired tonight and a lot of fans were left unhappy.

After nine years, while we finally found out how Ted Mosby (Josh Radnor) met "the mother" Tracy, we also learned the real reason Ted was telling his kids this long-winded story that barely involved the mother.

As many previously predicted, the mother passed away years ago, and Ted was trying to ask his kids permission to move on six years later with their long-divorced Aunt Robin.

In a way, it shouldn't come as a surprise since Ted's attraction to Robin was always the focal point of the show. The pilot episode even ended with Ted telling his kids, "And, that's how I met your Aunt Robin."

While Ted's kids were able to accept this, the twist didn't sit well with a lot of fans.

Looks like the true Final Slap was the writers slapping us in the face #HIMYM

so #himym could have ended after the pilot... they erased nine years of character development to get to... the end of the pilot...

Quote from Reddit that sums things up nicely: "I feel like I just found out my favorite love song was written about a sandwich." #himym

Do yourself a favor. When Ted says "And that kids, is how I met your mother". End the episode and pretend it cut to black. #HIMYM
