"Jennifer Ehle is fine indeed as the wife Serafina, voice and bodice a-tremble as she is racked between the demands of love and honour. "
"As Serafina, Jennifer Ehle's bosom heaves affectingly apparently possessed by a fear of death as much as dishonour, hardly surprising given that a figure of death in a red mask pops up at all the best parties."
"Jennifer Ehle - equipped with strikingly beautiful cheekbones and breasts - is so constrained by Serafina's high nobility that she almost never once sounds natural. "
"Jennifer Ehle, Douglas Henshall, Clifford Rose and others resist the temptation to send it all up, which is much to their credit: and John Carlisle goes further. His Don Juan ends up in one of those moral predictaments so loved by Spanish Golden Age dramatists. "
