"Tumanov stages modern drama paying not attention to numerous exclamations about its absence. Because plays become real drama only when somebody stages them".
(Alexander Platunov, "Petersburg Evening")
"He (Tumanov) is able to find an adequate scenic form for the world of associations and impressions reigning in plays, where the note is not less important, than the dialogue. Where characters need thorough portrayal, but at the same time do not bear thick realistic strokes. Where heroes are not separable from the atmosphere - unsteady, nervous, ironic and absolutely authentic."
(Elena Alekseeva "The Russian idea")
"Tumanov is a rare director who has a power field, which allows to create the steady world of illusive characters. He converts a fairy tale into a reality".
(Leonid Popov "Itogi")
