Ana Valles' plays are one of those propositions that capture us because she is capable of saying it all without telling anything and because she turns boldness and aesthetic transgression into her identity signs... Thunder & Mystery , as it is always the case with Matarile's plays, is refreshing because it hides from conventions and because it hides from the traditional drama arguments to undress the characters through what is, surely, one of the most productive resources of the arts: breaking boundaries between reality and fiction.
Inma López Silva. TEMPOS NOVOS

Thunder & Mystery is like an absurd ballet and, therefore, it is a place for freedom of speech. It entertains the public throughout, and there are also very intense and intimate moments where they burst out in tears. This play has the elegant atmosphere of funerals. It has the necessary irony to relativise the most serious topics. It is like going to a party where horror pulls the strings of events. It is like learning to speak about forbidden topics. Like talking about the great pain that being alive inflicts upon us.

... its scenic reality works with coding and enhancement systems perfectly assembled, making true the saying that art cannot be bound by words.
Xosé Lueiro. GALICIA HOXE

Matarile Teatro, putting forward Ana Valles's voice through her actors and through herself, makes a daring reflection about the meaning of art, theatre, the life of the actor and the historical perspective. A beautiful and vibrant staging full of nuances guides the actors that interpret themselves through their memories and their reflections, sometimes with sadness, sometimes with lots of humour. A bit of Kantor, inter-textual plays and lots of Thomas Bernhard from the distance pepper a proposition created from outside the text and supported on reflection. Brave, daring and full of truth. There is nothing to be more grateful for in these times of deception, than a truth told directly to your face.
Arianna Fernández. OPHELIA

The post-modern irony of these proceedings does not escape the viewer, and neither does the intellectual humour with which relationships marked by invisibility and deep solitude are faced (leniently but sharply), which in their deeply distressing nature become comical, and neither do some hurtful and relatively unsatisfied biographies that we do not want to take too seriously. To sum up, Thunder & Mystery is a bitter and cheerful show, which is a further step in Matarile's coherent and ambitious trajectory. Ana Valles continues researching the territories of her drama and intellectual obsessions, but she does it without repeating formulas. On the contrary, she undertakes new risks. But there is no doubt about her control of the situation and her confidence in herself. Just as there is no doubt about her originality and her extraordinary sense of drama.
