Kicking Blood (2021) on Netflix

When Anna, a centuries old vampire, watches Robbie, a charming but reckless young man, recover from his alcoholism, she decides to quit blood and restore her humanity.

Anna has been living in a haze of psychedelic blood bliss for as long as she can remember. Her hedonistic existence is challenged when she meets Robbie, a charming alcoholic party boy late one night. He is looking for a drink; she is looking for a feed; they bond. Anna takes him home, intrigued that Robbie doesn't care if he lives or dies. She decides to let him live and stay with her until he gets sober - putting her at odds with her true murderous nature and the wrath of her vampire clan. When Anna watches her best mortal friend die from cancer, she's inspired to choose life. Confronted by her cohort of vampires, Anna vows to quit blood and become human again for the love of life - and Robbie, of course. Anna, weakened by blood withdrawal, makes a run for it with Robbie as they are preyed upon by the vampires. In a final showdown, what it means to be human is put to the test.
