Saw this film at a rusiian film festival two years ago, and it was one of the stronger efforts.
As wpqx already pointed out, what stands out is the middle section with the wedding, but besides some great moments - I particularly liked the "ending" sequence, when the madwoman gets active, I also thought it too long and repetitive. As a whole, the film is put together from pieces that dont fit well. Two or three short films would have been a far better option. Nevertheless worth watching, though I hope Muratova has made some better films. If this is a minor work, a director to watch out for.
