To me it's a tie between Lost and HIMYM.

How I Met Your Mother ending easily considering they shot a a far superior ending but didn't go for it and ultimately the entire show was a complete waste with it ending with Ted/Robin,just passing over the mothers death and hell they spent an entire season based on the weekend of Barney/Robin's relationship only to end it twenty minutes into the last ep.

Plus, killing off Cristen Milioti should be considered a crime, that woman <3

This just had to be it. Even the alternative ending was horrible, in my opinion. Ted talks about his wife, for the entirety of 9 years, until she dies randomly..It just made no sense to me at all. Robin should have stuck with Barney from the beginning because even they both said that they had the "same mind together". The mother was incredible, wasn't annoying than Robin, and she was the perfect woman to just feature for the mother role. I wouldn't have mind Victoria being the mother as well because she was also incredible for Ted. But, sigh...

If Under the Dome doesn't get a third season, which, chances are, it won't... then the series finale was fucking hopeless.

Dexter from what I heard

I'm actually gonna use an anime and say it's Princess Jellyfish.  This show had a good premise, it waqs unique, and everything (and I literally mean EVERYTHING) just kinda gets dropped at the end.  I know a lot of animes don't have complete resolutions at the end of their shows, but this one didn't seem to have any at all.

HIMYM was an overrated Friends rehash to begin with, but it had a very strong, vocal fanbase which voiced their displeasure with the finale. I have to say I'd agree.
