This movie is a blast - true, it helps to be a fan of the Spice Girls, but then again if you're not why would you be watching this film in the first place?  The music is top-notch (although I'm still wondering why their cover of "Leader Of The Gang" seen in the film remains unreleased), and the acting is well done (in a sort of inexperienced Beatles / A Hard Day's Night sort of way).  No, it's not an Oscar contender, but is is fun.  As a former fan of the group (I gave up when Geri Halliwell left - she was my favorite) I recommend Spice World to anyone who wants to have a good time.  It's fun!
