In The Independent 22 May 2009 there is a discussion of playwright Tom Stoppard Is Tom Stoppard's Arcadia the greatest play of our age?
The introduction is interesting:
"What will endure from the plays of the late 20th century? Already, the theatre that caused the greatest fuss at the time- the in-yer-face shockers by Mark Ravenhill, Martin McDonagh and friends- look flashy and shallow and strangely dated; only Sarah Kane's psychological slashing seems to have survived from this flashing pack of playwrights."
I can agree with that. Ravenhill is becoming very tiresome now.
