Massofmen is an idiot of epic proportions but i will agree that over the past 10 years or so the West End has not really been putting out many musicals. Gone With the Wind died a death, as did Imagine This.
However we have had some great stuff like Zorro, Love Story, Bad Girls etc, whilst the shows may not have been big hits here they were still good shows. The problem is that original musicals are getting lost to the overblown rubbish like Wicked, Rock of Ages etc that have come from Broadway. Now producers are funding shows based on American films to keep the hen party audience happy.
Both countries produce their fair share of crap musicals, we just dont end up sending all ours over there, sadly we get a lot of the rubbish Broadway ones.
Also, i think the UK is far better at producing revivals of classic American musicals where great performances, innovative design, superb direction etc take precedent over big overblown spectacles. And yes, the UK is far better at plays recently though i adore a lot of American works.
America will always be better at musicals, i think the US actually takes more risks with musicals then the UK does, but don't make it sound like the UK does not do musicals anymore, as i say we just don't ship them over in a shiny merchandise driven package.
Matilda is a very strong musical, London Road is also superb, maybe try looking up musicals outside the US Massofmen, there's a whole world out there.
So can the country who gave the world Good Vibrations stop throwing stones at the country who unleashed We Will Rock You, we both suck equal at times, if anything we should be insulting those pesky Australians for giving the world Dirty Dancing and Priscilla (kidding, i love Australians)
Namo i love u but we get it already....you don't like Madonna
