A few weeks ago, The CW surprised us all with early guaranteed renewals for our personal favorites 'Arrow' and 'Supernatural,' as well as 'The Vampire Diaries' and freshman offerings 'The Originals' and 'Reign.' Not all of the network's series have been guaranteed additional seasons, but we at least have exact dates for their impending finales!

According to the network, the as-yet-unrenewed 'Tomorrow People' will close up shop first with a May 5 finale, while 'Arrow' season 2 will come to a close on May 14, the same week that features finales for new entry 'Star-Crossed,' 'The Originals,' 'Reign,' 'The Vampire Diaries' and 'Hart of Dixie' on their respective nights.

Closing out the pack will be 'Supernatural' season 9 with a May 20 finale, though new sci-fi tale 'The 100' will premiere just one day before on May 19, wrapping up all the way down the line to June 11. Additionally, new four-hour miniseries 'Labyrinth' will premiere Thursday, May 22 and close out on Friday, May 23. The adaptation stars 'The Strain' castoff John Hurt, 'Captain America: The Winter Soldier''s Sebastian Stan, 'Downton Abbey' star Jessica Brown-Findlay, 'Harry Potter''s Tom Felton and Vanessa Kirby.

You can bet that we'll be covering 'Arrow' and 'Supernatural' right down to the end, as well as their respective spinoffs, but what say you? Which of The CW's 2014 finales are you most excited to see?
