SLEEPY HOLLOW: Lt. Abbie Mills (Nicole Beharie, L) and Ichabod Crane (Tom Mison, R) go on a hunt to discover an unidentified boy's origins in the "John Doe" episode of SLEEPY HOLLOW airing Monday, Oct. 14 (9:00-10:00 PM ET/PT) on FOX. ©2013 Fox Broadcasting Co. CR: Brownie Harris/FOXFox has canceled "Sleepy Hollow" after four seasons, and Twitter is throwing a party. Some fans -- really former fans -- are downright gleeful, still fuming from the show's major changes, especially killing off co-lead character Abbie Mills (played by Nicole Beharie) in the Season 3 finale. The #sleepyhollowisoverparty is justice for Abbie/Nicole.

Tom Mison led the series as Ichabod Crane, and his chemistry with Nicole Beharie helped put the series on fans's radars back in 2013, giving the premiere 10 million viewers , averaging around 7 million for the 13 episode season. But ratings dipped from there, especially in the drastically different Season 4, which struggled to maintain 2 million viewers a week. The Season 4 finale aired on March 31, and viewers seemed to be expecting a cancellation notice from Fox. According to TVLine, it came on May 9.

Fans seem to love the cast, but not how the show treated the characters, and now look forward to better for the stars involved. Here are some reactions to the news:

"Sleepy Hollow" was the second cancellation from Fox this week, after "Rosewood."
