If you like musicals you'll love it, a real send up of great films. Some of the music is modern and not all to my taste, but the acting and dance is brilliant, spot your favourite musical in it. If you don't like musicals give it a miss as you probably will not be able to follow it.
I like the actor Paul Nicholas and wanted to see him in a different roll. A 'fluffy' film that entertained me, if you like Paul it is worth a watch, not upto 'Just good friends' standard but better than a lot of stuff on tv nowadays.
