Showtime's "Penny Dreadful" came to an end on Sunday by killing off one of its major characters. The two-hour special saw Eva Green's Vanessa dying and it looks like the series has also wound up with the death of its main protagonist, as the episode ended with the words "The End."

There hasn't been any official word on this, but showrunner John Logan had earlier noted in an interview that "Penny Dreadful" was about Vanessa and her journey.

"People will ask me, 'What is Penny Dreadful about?' And I'll say, 'It's about a woman's journey to faith,'" Logan told Entertainment Weekly at the beginning of Season 3. "It's about Vanessa's relationship with God — that's the most important relationship in the piece. And last season she took the crucifix off her wall and burned it. She's lost her faith, essentially. And even this season, she's lost. She's a mess. And from the wasteland of non-belief, she has to find a way back into some faith — faith in herself, faith in God, faith in her friends."

The fate of "Penny Dreadful" remains a mystery, but the finale did tie up a number of loose ends. For instance, viewers finally learned how Brona Croft's daughter died -- the baby froze to death while Brona was lying unconscious in an alley. The finale also revealed that Kaaetnay is also a werewolf and it was he who turned Josh Hartnett's Ethan into one in the hopes that he would one day save the world.

Meanwhile, fans of the show have been taking to social media to express their displeasure at the show's ending, with some saying they feel betrayed.

"This is so heartbreaking and disappointing," one fan noted. "There was SO much more potential to continue the series. I know they could have find a way to bring her back and have her be stronger than ever. I felt so unfulfilled. There were so many unanswered questions I feel."
