Sarcasm is mostly a question of style I'd say. Patronizing, yes, maybe. Although he called himself a cranky old man in that article, so everything after that should be taken a grain of salt.
Emma herself attributed most of her success to chance in that interview (if he quoted her correctly). It's a case of "see, I'm putting myself down all the time so please don't do it too, and maybe say something nice about me". He just didn't. That seems to prove his point that Emma is "looking for nurture". Arguably, that's not a particularly clever insight, as I think you can easily get this impression of Emma with her polite manner accentuated by her small frame and young face. But it seems to be true. If he just wanted to be a dick he could have taken some potshots i.e. at her lemons and lemonade line (I thought he did, but looking up trenchancy it just seems to mean forcefulness ). He just went overboard with implying how unimpressed he was with her; implying that she has to prove she's worth the hype. And that's probably the case.
''So, Watson will always be, for me, a nice middle-class English girl pretending to be another nice middle-class English girl who’s lucky enough to have magical powers for which she’s extremely grateful.''
Emma is right. This isn't fair to do, the guy was a total dick writing this whole crap of article. There are no q&a's just quotes, I don't even trust it, he could have twisted everything; like ''Nowadays Emma Watson is set to make a lot more lemonade, and as I left her I thought: I damn well hope it’s potable — then checked myself. After all, why does it matter to me? Unlike with her earlier screen incarnation, I will not be compelled by my children to witness these ones. No, I can decide to watch her movies or not, as I choose, just as she has chosen to become a real grown-up actress. And that, surely, is what cinematic art should be: an act between consenting adults.'' I for one won't read it again.
You and Jonny should consider leaving the forum because you are anything BUT fans, I think you belong to Pottershots.
