Keep it that way.
I'm interested in watching it completely independent of the other two films. I've not watched those in years, I've not had a day to dedicate to them!
If it's a 7/10 as a stand alone then surely worth a go?
It's not a terrible movie.
But as I said on the previous page, because Coppola made it purely for monetary reasons and because Paramount then **** him over on the length of time he was allowed to write the script, it is (a few great scenes aside) a bit of an uneven mess with some of the worst acting ever committed to film in the shape of Sofia Coppolas 'performance'.
