This was so much all at once. It was fantasy, but modern, with an Arthurian-feeling prophecy or legend or something, but also sci-fi-ish elements because there's definitely some weird medical stuff going down with that hospital and a dude that Benjamin-Buttons his way through life while time travelling??? There was just a tiny bit of everything, enough to have you fascinated but not enough to let you know what on earth was happening. So basically I'm hooked because I need to know what's going on!!!
