I think Master of the House
and Beggars At the Feast
need to be left in otherwise we have a story where nearly everybody dies (a very high body count for a musical which includes a young boy) and both add a much needed levity to the story. While Dog Eats Dog
does really bring to light the very dark and cold heart of Thénardier.
It has been said before and if it must be cut, I think a cut of the musical should be made that is much like The 10th Anniversary Concert.
People are willing to watch movies of 3 hours with an intermission. Many movies are reaching the 2.5 hour mark an extra 0.5 hours shouldn't be a problem.
