From wikipedia

Since its world premiere at the Berlin International Film Festival on February 14, 2007, in front of 1,700 audience members, 300 has received generally mixed reviews. While it received a standing ovation at the public premiere,[67] it was panned at a press screening hours earlier, where many attendees left during the showing and those who remained booed at the end.[68] Critics were, and still are, divided on the film.[69] On Rotten Tomatoes the film has an approval rating of 60% based on 232 reviews, with an average rating of 6.08/10. The site's critical consensus reads, "A simple-minded but visually exciting experience, full of blood, violence, and ready-made movie quotes."[70] On Metacritic, which assigns a normalized rating to reviews, the film has an average score of 52 out of 100, based on 42 critics, indicating "mixed or average reviews".[69] Audiences polled by CinemaScore gave the film an average grade of "A–" on an A+ to F scale.[71]

Some of the most unfavorable reviews came from major American newspapers. A.. O. Scott of The New York Times describes 300 as "about as violent as Apocalypto and twice as stupid," while criticizing its color scheme and suggesting that its plot includes racist undertones; Scott also poked fun at the buffed bodies of the actors portraying the Spartans, declaring that the Persian characters are "pioneers in the art of face-piercing", but that the Spartans had access to "superior health clubs and electrolysis facilities".[72] Kenneth Turan writes in the Los Angeles Times that "unless you love violence as much as a Spartan, Quentin Tarantino or a video-game-playing teenage boy, you will not be endlessly fascinated".[73] Roger Ebert, in his review, gave the film a two-star rating, writing, "300 has one-dimensional caricatures who talk like professional wrestlers plugging their next feud."[74] Some critics employed at Greek newspapers have been particularly critical, such as film critic Robby Eksiel, who said that moviegoers would be dazzled by the "digital action" but irritated by the "pompous interpretations and one-dimensional characters".[64][75]

Variety's Todd McCarthy describes the film as "visually arresting" although "bombastic"[76] while Kirk Honeycutt, writing in The Hollywood Reporter, praises the "beauty of its topography, colors and forms".[77] Writing in the Chicago Sun-Times, Richard Roeper acclaims 300 as "the Citizen Kane of cinematic graphic novels".[78] Empire gave the film three out of five, writing, "Visually stunning, thoroughly belligerent and as shallow as a pygmy's paddling pool, this is a whole heap of style tinged with just a smidgen of substance." Comic Book Resources' Mark Cronan found the film compelling, leaving him "with a feeling of power, from having been witness to something grand".[79] IGN's Todd Gilchrist acclaimed Zack Snyder as a cinematic visionary and "a possible redeemer of modern moviemaking".[80]
