Well - TNT

Although the focus tends to go somewhat fuzzy towards the end, I rather warmed to American Lisa Kron's short and surely autobiographical play, thanks in no small measure to an engagingly sympathetic performance from Natalie Casey as a younger Lisa.

With a mixture of affection and exasperation which will ring a bell with many daughters, Lisa tries to unravel the process by which she herself managed to become well, whilst Ann (apart from one brief period when she tackled the racial ills of a whole neighbourhood) has remained crippled by debilitating allergies for as long as she can remember. Armed with prompt cards, she attempts to orchestrate a "multi character theatrical exploration" of illness and wellness. But events aren't completely under her control as, in the way mothers do, Ann fussily interrupts the proceedings to offer hospitality and suggest corrections, and the quartet of hired actors (all excellent) not only slip out of their roles as neighbours, doctors and fellow allergy suffers but also appear as characters she really doesn't want to include.

Quirky and unusual, Eve Leigh's playful production is full of little surprises and gentle humour, and in the intimacy of this tiny studio space, it's easy to believe that we really are guests invited into the Kron's living room where Sarah Miles' chronically fatigued Ann spends her days wrapped cosily in a blanket.
