[The film] ends with what can only be called an utter non-sequitur, a non-verbal scene with so little tangible connection to what came before it that it’s impossible to settle on a definitive interpretation. Not that that’s stopped people from trying, and I’ve seen many compelling readings of that scene, but I prefer moments like that to retain their mysterious aura, their potential for branching out in multiple different directions at once.
