The easy verdict - it is a David Lynch ! This explains all and offers some comfort to viewer.
In fact, it is a Ionesco play. Or a sitcom reduced to its essence. Three rabbits in a room. Their words, without sense, prepairing the audience for a presumed revelation of a secret. But, except the entries of father/ husband, the laughts from public and the rolling words saying just nothing, in fact, but offering powerful images , maybe , nothing.
So, easy to see another show. But fascination / curiosity just works well in this case, the rabbit heads - and their shadows - , like the creepe voice in dark are good points and you have the privilege to craft the coherent story, from the recipe of The Others bz Alejandro Amenabar to Who s afraid of Virginia Wolf ? Or. Waiting for Godot .
