"Tomas" (Franz Rogowski) and husband "Martin" (Ben Whishaw) find their marriage severley tested when the former man starts to fall for "Agathe" (Adèle Exarchopoulos) and that passion drives "Martin" into the arms of "Amad" (Erwan Kepoa Falé). What now ensues is, frankly, a rather dull introspective of characters that didn't really leap off the screen at me. Rogowski can be a charismatic actor, but here is offers us a rather unremarkable characterisation of a horny man who wants to have his cake and eat it. Whishaw is, routinely these days on screen, just a bit weedy and offers us another weakly constructed individual who seems content not to fight for the man he's supposed to love. It's all just rolls along without really catching fire, it's over-scripted and though it may well have a visual authenticity to it, it's all just a bit so what? The production and pacing all contribute to the general ennui of the whole thing and to be honest, I was just a bit disappointed with this whole thing. I saw it at the cinema this week, but I suspect even the most ardent fans of these three can wait for a television screening.

More promise than execution, "Passages" tackles twentysomethings navigating gender fluid sexuality with Paris as the backdrop. Welcome to the Tomas, Martin and Agathe dance. Narcissist and disagreeable German film director, Tomas is the unfortunate rotten core here. His marriage to Martin is disrupted by a purely sexual tryst with fetching schoolteacher Agathe, and Tomas can't wait to gush about his walk on the straight side to his husband. Things don't go well.

An interesting premise for sure, but one that plays out sloppily, without any character development to speak of, unless Tomas' deplorable indifference counts. An ugly persona, with an appearance to match - a patchy beard, gaunt features, a snaky lisp and a horrific wardrobe (which ironically, is getting kudos from GQ) - it's a bit of a puzzle as to his alure. Surprisingly, he's quite dull to boot, which makes for an odd protagonist: a difficult one to hate, or care for.

"Passages" takes stabs at the French New Wave, dishing up randy youth moving aimlessly through Paris to a jazzy backdrop, but with the exception of a lovely, film-closing evening bike ride, doesn't hit the mark. Without style, the absence of substance dominates this lackluster experience.
