[EX Q]: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.
[EX A]: Positive

[EX Q]: I was extremely disappointed with this movie. The story had no sense of direction. It seemed too badly glued together, as if the scriptwriters were just adding more things as they went along, saying, "we'll make her a divorced woman...and then we'll make her go on a gay tour...and oh wait, let's make her have no morals and have sex with a man she hasn't known for even one day...and lets make her flirt with the married real estate man." All in all, the story turned out to be pretty stupid with nothing to admire in the main character.
[EX A]: Negative

[EX Q]: All the interspersed kid and parent interviews where they talk about all the trains they have just feels like a thinly disguised effort to sell more product.It's also AWFULLY frustrating that you can't jut buy the DVD Series here as you can in the UK, but have to make do with compilations where there are invariably episode duplications.*sigh*

Negative
