Simply put, Michael Crawford is a god. Good old Colm can't measure up. Without even knowing the lyrics or the musical itself, you could tell the pain the Phantom was going through just through Crawford's voice. Colm sings with no or forced emotion, while Crawford's voice flows majestically and soulfully over the notes and the words.
Sara Brightman's pure soprano is angelic, as opposed to the other Christine's vibrating train wreck.
That and the words were changed for this CD...
I'm sorry...this is a disappointment. Buy the original, people!
