That's more or less how I see it - although I suppose I don't have the same amount of background to go with it - I was honestly starting to think I was quite alone, ha. I'm still not sure what to make of the play (of course I have not seen it staged, and incidentally I have not seen la Terreur et la Vertu either, woe, these things are lost on me) - well, I don't recall it as well as Thermidor (I recall that I was reading it in a dentist's office though) but it was very strange, parts are utterly different from Danton and then you come across something that was obviously absorbed directly into the film. Oh dear, and now I can't remember where I was going with that, so I'll leave it there. Anyway, I don't think I have anything to add.
...you know, that must be it.
