When I first looked at this edition, I thought "What the hell is this?!" Now, it is my favorite Entfuhrung of five. Yes, it is new, and odd, and different, with every singer having a double - with a lot of irony and double-play - with the evocation of many different symbolic levels. I understand why some of the reviewers hate it. It takes getting used to. (Although I think it rather unfair that one reviewer sends in his or her negative review three times!)
But, consider! Here we have the very best Osmin, an extremely effective Pedrillio, the very best Blondchen, and one of the best Belmontes ever. It is worth buying the DVD just to watch Brachts do Osmin. Amazing.
The creative and interesting staging means that the songs never, ever seem long. Nor is the staging irrelevant: it makes one think over the meaning and associations of the songs. Having doubles allows one twice the comic amusement: the interplay between the two, the "singer" and the "actor", is often very, very funny. And yet: great, great singing.
I am personally much less fond of the Konstanze, but this is, as always, a matter of taste. The all-talk part of the Sultan is also less successfully done, in my opinion: without a "singing" double, no comedy at all. The man is, as a result, dull. But the rest - I watch this edition again and again. It is definitely worth at least a try!
