Charles Perrault’s 2,500-word story Cinderella has been adapted in a number of animated and live-action films over the past several decades, and director Kenneth Branagh’s latest rendition features all of the classic elements that fans of the fairy tale have grown accustomed to. While critics have praised Branagh for bringing an air of enchantment to all of those old and familiar parts of the story, some are questioning whether his unique additions take away some of the magic and make the film too long for young viewers to enjoy.

Just like in the classic 1950 Disney animated film, Branagh’s Cinderella revolves around a cindered young girl, her wicked stepmother and stepsisters, a fairy godmother, and a charming prince. While the Wall Street Journal noted that Helena Bonham Carter struggled with the delivery of the godmother’s lines in their review of the film, they echoed the general praise Branagh’s cast has been receiving from viewers and critics alike, and noted that Lily James was the perfect fit for the title role.

“Impossibly lovely, be she cindered or begowned in cerulean splendor, and possessed of a luminous spirit that burns brighter than her backlighting,” wrote the Journal‘s Joe Morgenstern.

While the characters and important elements like the Prince’s grand ball all reach or exceed the bar that previous adaptations of the fairy tale have set over the years, Branagh’s attempts to add backstory and realistic motives for several of the characters may have made the film too long for children. Cinderella is a 112-minute film, and much of the film is spent exploring new political elements and the title character’s family history.

“The additional elements don’t add to the experience,” noted the San Francisco Chronicle‘s Mick LaSalle, who believes Branagh should have resisted the temptation to delve deeper into characters such as Kate Blanchett’s wicked stepmother. “The story as we know it is already in perfect balance, a tale of purity and innocence in conflict with evilness and cynicism.”

Cinderella officially releases in theaters on Mar. 13, and analysts with Variety anticipate the film earning a strong $60 million during its opening weekend.
