BDSM comes in many forms which have nothing to do w/ leather. SPOILERS DDL was a control freak who needed to be controlled. I sorta felt like the film promised an ending that it didn't really deliver but I still enjoyed the journey and did basically like the quirky nature of that ending. It seems a little out of left field (or rather, out of another movie) but I ultimately think it basically works, that PTA had given us enough to be able to just roll w/ it. As I've said before, the writing in PTA's films frustrates me more often than not but I consider "Phantom Thread" to be one of his best films and the screenplay, though pretty bare bones in some respects, was definitely part of that, though it maybe has more to do w/ the lack of embarrassing scenes than anything else.
