I'm not an expert on Shakespeare by any means, but between friends who do community theater and my Renfest phase, I have probably seen most of the plays live! I haven't seen many of the big recent adaptations though; I always kind of meant to get to the Whedon one, but I came to the Tate/Tennant one first. (And some of the stuff that's come out since about how Whedon dealt with his "friends" makes me wonder.)
