darquegk,I agree with what you said that spectacle done live gets a better reaction from the audience, and well said too.
For me, the only gripe that I have regarding mega musicals, is when they use elaborate sets and costumes to make up for flaws in the book/score. A perfect example of a show that does this is Phantom. Phantom is a show that I feel has a weak book and score. But, that's not something one usually notices as they are too busy looking at the beautiful sets and costumes.
In my opinion, just because a show is a mega musical, doesn't mean that it is covering up for flaws in book or sore. A perfect example of a show that does this is Les Miserables. Les Miserables is all sung through like an opera. And, like an opera it depends totally on its beautiful score to tell the story. I feel that you can have a great production of Les Miserables without the turntable or large set, and still have a very moving and beautiful production of Les Miserables.
That is why when Les Miserables announced its 25th anniversary production, I was not one to get up in arms that they weren't using the original staging and sets. This is because they still the amazing and moving score that is vital to the story. And, that wasn't changing. Phantom on the other hand, their new tour has me a bit worried. I fear that because it's a faulty show, and because it doesn't have the same elaborate sets as on Broadway. I predict that because it doesn't have the same sets as on Broadway, it may highlight the flaws of the show that were otherwise covered by the original design. Just my two cents.
