...other than a conversation I just had with Nick M and a desire to think about something other than the Oscars for five minutes here are my 5 favorite plays (ask me tomorrow it'll be different). I'm not claiming they're the best productions I've ever seen (in some cases I've never completely loved a production of said piece) or the best ever written. Just the five I have the deepest affection for currently. If you want more than five, just add anything by Albee or Williams to the shortlist.
"ANGELS IN AMERICA" Tony Kushner
"CAT ON A HOT TIN ROOF" Tennessee Williams
"THE CRUCIBLE" by Arthur Miller
"MACBETH" by William Shakespeare
"WHO'S AFRAID OF VIRGINIA WOOLF" by Edward Albee
For people who know theater better than I, send me suggestions of things I should read (obviously this list is very mainstream in it's "best" way.)
