They're saying: Globe-trotting appeal let down by over-stuffed story.

No one in the cast has really been singled out in any consistenly positive way.

With a multilingual cast of mostly unfamiliar faces, plus a few stars, "360" feels too abstract, orchestrating break-ups and hook-ups in a passionless vacuum. For screenwriter Peter Morgan, it's the same problem that plagued "Hereafter" spread across an even more unwieldy ensemble.

The individual vignettes are handled with a masterful eye for composition and pacing, but "360" has so little emotional resonance beneath its coincidences, ironic parallels, and "hey, ain't life random?" musings that you mostly sit there wasting time thinking about composition and pacing. Meirelles is an immensely talented filmmaker, but with "360" he's a filmmaker too busy throwing his talent around in a showy way.

The film is inspired by Arthur Schnitzler’s classic La Ronde, but is elegantly updated by screenwriter Peter Morgan and director Fernando Meirelles for a modern-day medley of stories that take in love, passion, chance, temptation and friendship all set against a stunning backdrop of vivid locations.

With a starry international cast and multinational locations, you never take your eyes off the screen for a second. On the other hand, this is a cold and cerebral movie, where one’s attachment to any particular character or story is tentative at best. You watch the film rather than get absorbed by it. It’s art house with Hollywood credentials.

It’s another tired anthology of uninspired vignettes that show us how we’re all connected especially if the script is written that way. The movie manages to waste a talented cast, its director’s abilities, and two hours of the viewer’s time.

Hey kids, did you know that even though it feels like we live in a bubble, all of humanity is actually interconnected? In fact, every little decision we make can actually have an impact across the globe. Mercifully the deeply disappointing, multi-character mosaic movie 360 stops short of actually saying that regurgitated nonsense out loud though sadly the well worn theme is hammered home so hard that it might be a good idea for theater owners to hand out vomit bags with each purchased ticket.

Like Crash, Traffic, and a number of similarly styled films, the many stories in 360 share a thematic thread, but this one is looser than most. The film also unravels a bit at the end, undermining what should have been a tense dramatic moment with a light and goofy score. The visual treatment using reflections and seamless split-screens does grease the story along, but when the film finally comes full circle, it stops short of saying anything profound.
