Netflix has released the much-anticipated second part of You's fourth season and viewers are divided over its conclusion, which has been described by fans as "insane".
The latest season saw serial killer Joe Goldberg (played by Penn Badgley ) relocate to London, where the lead character reinvented himself as Professor Jonathan Moore.
It has introduced viewers to a host of new characters, including the latest object of his affections Kate Galvin (Charlotte Ritchie) and author Rhys Montrose (Ed Speleers).
The first part of the season was released on the streaming platform last month and fans had to wait four weeks to watch the remaining episodes, released today (March 9).
** WARNING SEASON FOUR, PART TWO SPOILERS AHEAD **
The second part features murder and twists, including that 'serial killer' Rhys is actually a figment of Joe's imagination - with him back to his murderous ways once again.
Towards the end, Joe admits to Kate that he's killed people and they both promise to "keep each other good". And he seems to confess everything about his past to her.
The ending shows the pair together in New York. Joe has seemingly been able to return by blaming late wife Love Quinn (Victoria Pedretti) for events from their past.
He however teases to viewers that he hasn't changed and appears to have simply accepted his dark side - which could lead to more murder if You returns for a fifth season.
Viewers appear divided over the ending, with some impressed by the conclusion to the fourth season. The ending has been described as "insane" by fans on social media.
One viewer tweeted earlier: "They kinda lost me mid chapter but the ending was complete chefs kiss. No spoilers from me but genuinely impressed".
Another wrote: "THE ENDING OH MY GOD WHERE IS SEASON 5 RENEWAL ANNOUNCEMENT," while a third said: "Well I didn't see that coming. Loved the ending - season five will be even more deliciously evil".
"Joe accepting his sick self in the end is crazy of them to do and totally amazing," said one fan.
Another said: "Just finished [it]. Twists, turns, shock, surprises.. had me absolutely shook by the end? Seriously well done to everyone, what a show, can't wait for series 5".
"Part 2 was honestly insane, reeled me in with its crazy plot twist and now I desperately want more," tweeted another. Another commented: "Part 2 was insanely good."
Others however have been left unimpressed by the ending, with one person tweeting: "Absolutely hated [it]," while another said: "Nah I'm actual disappointed in the ending it seemed so rushed".
Season 4 of You is now available on Netflix.
