This is my favourite ALW musical, probably because it is the show that I liked most. I bought a "restricted view" ticket and to my surprise, I was not located behind a pillar, 1000 meters from the stage, but I was sitting right in the very first row, a meter away from the stage and the orchestra pitch ("too much view" rather than "restricted view") and it was a really breath-taking experience.
If "Phantom of the Opera" was Webber's attempt to marry grand opera and musical, this is his attempt to introduce chamber music to the musical. It is an intricate interweaving of themes and variations (as in chamber music). This creates a more intimate atmosphere, rather than the overwhelming pathos that usually is a characteristic of musicals. I think you need a little more time to get used to this sort of musical, but if you take the time then it is really rewarding, with lots of gems - and I do not mean the hits "Love changes everything", but rather things such as "There is more to love", "Mermaid song", "Memories of a happy moment" (if I remember the title correctly), "Seeing is Believing".
