Spoiler Alert: TV Finales That Made Fans Furious

Felicity

The issue with Felicity was a unique one. The show had actually already finished filming its episodes, including the perfect series finale, when the studio decided to add on five more episodes.

Stuck and unsure what to do, JJ Abrams went with a time traveling storyline that had Felicity traveling back a year earlier to change the future.

The story arc felt very out of place (because it was) and kind of stomped all over the actual finale that had been planned. Luckily, the show was able to still wrap the series up exactly the way they wanted to despite the detour getting there.
