The trailer + Coppola's filmmaking history = Made absolutely no sense to me.
I am not familiar with his early films, to which 'Twixt' is allegedly a form of return. Nor did reading reviews help, since people seem to have the most conflicting viewpoints on this opus.
My very own viewpoint, now that I have seen it : I liked it a lot! Not sure why, though..!
It sort of blended elements from 'Twin Peaks', Edgar Allan Poe, horror films, poetry and Coppola himself, with a hint of 'The Shining'.
I realise it sounds unorthodox, and it was. I do appreciate that in a film!
