I loved Starlight Express when I saw the first national tour in the 80s, but when I saw it in London in 1999, it was awful. The show itself is not bad, but the entire cast phoned in their performances and the audience talked throughout the entire show. The changes in the book and score were completely unecessary and I feel that, other than Crazy, weakened the show. Technically, it was an innovative show that brought many spectacular new elements to musical theatre. I would love to see it return in its original version.
As for STOMP, well, it is sheer brilliance if you have an appreciation for dance, ingenuity and rhythm. There have been numerous knock-offs since it first opened, so it may not have the same jaw-dropping affect it did then, but there is no denying the talent behind its performers and its creators.
PS - A hopper car on a train is a freight car with a floor sloping to one or more hinged doors for discharging bulk materials. That's why they are called "hip hoppers", which actually makes more sense than "rockies".
