Whether it's a 97 release or a 98 release (technically Boxing Day 1997 in the UK) Spice World is really not a film for everyone. Though initially it seems to just cater to those who love the pop and power ballad playfulness of Britain's seminal girl group (sorry Little Mix!), Spiceworld is a comment and critique on so many things. The music industry, feminism, the power of friendship, the power of film and media in general, and even the power of the flash back and flash forward.
Spiceworld is a movie that is both serious and silly. It's camp and drama. It's a mockumentary but it's also an advertisement tool for an album (or vice versa). It's all those things and more which is why often you find people really love it or there'll be those who find it to simply be Too Much.
In whichever camp you live in, it's undeniable that the themes of Girl Power, tongue in cheek play, and the unused script idea that would become Viva Forever! (a totally not Spice Girls jukebox musical) is not something you can ignore. And maybe that's all for the best.
