I think it’s rather funny, how in the discussion about the adaptations of Pride and Prejudice from 1995 and 2005, it is so very frequently claimed that those who prefer the 1995 version do so because of Colin Firth, whereas those whose main concern is Lizzy prefer Keira Knightley and the 2005 film…
whereas I just absolutely adore Jennifer Ehle, while I don’t care very much for Knightley’s Lizzy (though I don’t dislike her—she’s Lizzy all right, just without the brilliance of Ehle’s performance) and I actually find Colin Firth’s performance as Darcy—though certainly very good! as he is an expert actor—to be one of the weaker aspects of my otherwise favoured adaptation. In fact, I nearly prefer Matthew Macfadyen’s Darcy… simply because I prefer his vibe.
On the other hand, his performance, though I generally like him a lot, is comparably bland, just like Keira’s. But my critique of his performance is the opposite of Firth’s: Darcy needs a balance of actual mean snobbery and well-meaning awkwardness, and Firth is mostly the former, Macfadyen the latter. That is, I think, also the reason why both appear to specific, different groups of fans. Both are good Darcys, but with distinctly different appeal.
I actually think the 2020 version of Emma is in many ways like 2005 version of Pride and Prejudice—though not as good—and equally popular on the internet, because the characterization of the leads is so very adjusted to the taste common, modern taste. (I suppose I am an exception!)
As for Mr Darcy, I would even go so far and say that Laurence Olivier’s version had quite a good snob-awkward-nice balance, maybe better than any other Darcy I’ve seen. And Greer Garson is a very lovely Lizzy, even outshining him, though only almost as perfect for the role as Jennifer Ehle.
Anyhow—I really like both the 1995 and 2005 versions in different ways, and all four leads, too. It’s just that my preferences and reasons for them don’t really align the way that people usually claim they always would.
