Joel Lake’s review published on Letterboxd:
Rock The Kasbah is Bill Murray trying his best to work with a story about an aging rock manager that meets an undiscovered gem with dreams of being a star. Murray tries hard to make the story work but the film is tonally all over the place and the people of Afghanistan played out as one note characters that any story premise revolving around the Afghan culture comes off as being disingenuous. Kate Hudson is playing the love interest to Murray here and it jusn't work too well(even though I thought she brought a decent performance to her odd role). Zooey Deschanel's character is more of a plot device to get the story started instead of being a memorable character and Bruce Willis plays a satire of some of his other roles(but maybe playing it like he cared a little about the role as opposed to some of the films we've seen him in as of late).
The story seems like something audiences have seen before and done better(especially the inclusion of a foreign version of an American show being a main story element, this time American Idol-that was done much better with"Who Wants To Be A Millionaire" in the Academy Award winning Slumdog Millionaire) and the mishandled of the Afghan culture as well as the strange tonal shifts, Rock The Kasbah has no idea what kind of film it wants to be and delivered an underwhelming film as a result.
