The fuck? (pardon the pun)
It's actually impressive how diabolically terrible '365 Days' is. I had heard small details about how sexual this was but hadn't seen anything about the film's other aspects. Now I know why, there aren't any.
It's just one big illicit romp with practically nothing holding it together, a cynic would say this is Netflix just getting pornography on their platform through the back door (pardon the p... nevermind).
The worse part about this is the glorification of sexual violence, whether it be kidnapping or even - startlingly - rape. How the plot plays out is actually extraordinary - it turns out THIS is the way into a would-be lover's heart... who knew?! It's crazy. You could argue it's a sexually explicit retelling of 'Beauty and the Beast', but that's an argument for another day.
They could've done this without the aforementioned and still got the same vibe out of the film, it's bizarre why they choose to go down this direction. You can make characters hate each other before jumping into bed together, you simply do not need the criminality aspect. 
If I were to offer minor solaces of 'praise' about this 'film': the music (random Mabel is random) and the end scene, which is well shot.
