As to Emma Thompson, my feeling is that she's a pro's pro and could give you any reading you asked for.
True, but it's not as if Kushner was uninvolved; if he didn't like it, I suppose he could have whispered something, and he didn't. Presumably like you, I had Kushner's preface note in mind...the one where he indicates the angel should be terrifying and awe-inspiring at all times, or whatver it is he says (I'm too lazy to run upstairs and get the book to see the exact wording). Thompson's angel wasn't that, and -- heresy, I suppose -- I think that in the hospital scene, Streep eliminated any chance of her being either by Streep's (for me) similarly campy performance. And yeah, some of it was the direction, too: by playing the effects the way he did (and here I guess he stuck to Kushner's original intent, though that was for the stage and not for Hollywood), Nichols made it harder to concentrate on the performance. I guess for me, the difference was that unlike most of the rest of the cast, I felt I was watching her Act™. Not all the time, but some of the time.
I found some of Prior's material better played for wry humor instead of straight angst
In the version I saw, that was more the tone taken by the actor, so the HBO performance seemed familiar to me in this regard. Though a lot quieter, obviously.
I found the play insufficiently transformed
You know, as in Chris' example I
did have crappy seats the first time I saw
Perestroika (though not
M.A.), and I think that has something to do with how I responded to the intimacy of the HBO version.
I think, though, that the play has such a gut-slamming initial impact that it's almost impossible to recreate that, no matter the medium. I also think it's tied to it's time in ways that aren't so easily disentangled. But we've covered all this already.
