I haven't yet seen 'The Greatest Showman', though quite looking forward to it.
However, like another poster on here, I really can't abide 'Mama Mia' - can't think of anything endearing about a woman who was stupid enough to casually sleep with THREE different men in the same month without taking precautions! On top of that, I was never actually an Abba fan, in the first place, so the music doesn't even have an appeal for me - in fact, I'd find it very off-putting.
Despite saying that I was never an Abba fan, I absolutely LOVED 'Priscilla Queen of The Desert' ;-)!
