'Decadence, ambition, and the wild heartbeat of 1920s Hollywood, "Babylon" is a film that captures a frenetic maelstrom of excess with an intoxicating allure. Director Damien Chazelle plunges us into an era where glitz and glamor were shadowed by the precipice of moral and creative chaos, orchestrating a cinematic symphony that riffs beautifully, if not a trifle too long.

The film, a glittering tapestry woven with the lives of its eclectic ensemble, harkens back to a time when Hollywood was reinventing itself, unbridled by the censorship and constraints that would come later. Brad Pitt, exuding the old-world charm and weary magnificence of a silent film star facing the twilight of his era, anchors this tale like a sun around which the other comets orbit. Margot Robbie, fizzing with the kinetic energy of a starlet who embodies both the luminosity and the volatility of the era, gives us a performance that dazzles with raw power and vulnerability. Newcomer Diego Calva brings a fresh sincerity, his eyes a mirror to the audience, witnessing the wild ride of this gilt-edged carnival with wonder and growing disillusionment.

The supporting cast, including the poignant turns by Jovan Adepo, the electric Li Jun Li, and the ever-formidable Jean Smart, add their voices to this homage to the roaring twenties, each one contributing to the cacophony of ambition that becomes the overarching aria of "Babylon".

However, the effervescence of the party cannot hide that the revelry is long, perhaps an hour longer than necessary. Though each scene is crafted with decadent detail and the narrative arcs of the characters fold into one another like the layers of a complex dessert, the storytelling can occasionally feel meandering and overly indulgent.

The score awarded to "Babylon" reflects the unruly juggling act that the movie performs, balancing between brilliance and bloat. A 7 out of 10 seems fitting, for while it holds the attention and often astounds with its audacity and visual feasts, it does test the endurance with its length. But akin to a night out that stretches into the dawn, where the shimmer of the party lingers despite the weary bones, "Babylon" leaves its mark. It is a bloated beauty, excessive certainly, but undeniably captivating in its portrayal of the heady ascent and the inevitable plummet of Hollywood icons.

In conclusion, "Babylon" is a rollercoaster through the playground of early Hollywood's highs and lows, a place where dreams were larger than life and the appetite for excess knew no bounds. Despite its time-testing length, the film remains a compelling watch. It's good to see a movie brave enough to waltz with indulgence and grandeur, less concerned with brevity and more with the urge to swallow the era whole. For those willing to commit to its lengthy affair, "Babylon" offers a feast for the eyes and a thought-provoking reflection on the cost of unchecked ambition.
