Just back from seeing the film and I LOVED IT! I saw the stage show about 10 years ago and it was great hearing all the songs again. I thought all the singers were absolutely fabulous apart from Russell Crowe - but I had been led to believe he was a total disaster and massacred all the songs. I thought he did fine - apart from 'Stars' which was a real disappointment (such a beautiful song). He really looked the part and super hunky in his lovely uniform. I don't think he disgraced himself with his singing at all. He was hardly Pierce Brosnan in Mamma Mia 
Thought Hugh Jackman's voice was about 90% great, a few wobbles though. The start of 'Bring Him Home' was not good.
