“Meander” (*** out of four) was an elegantly done horror thriller about a young woman (Gaia Weiss) who finds herself locked in a strange tunnel full of a series of interlocking and increasingly convoluted traps of which she must escape while her unseen tormentor looks on. Yes, it’s one more derivation of “Saw” but this is elevated above its grimy origins by artful and compact direction from Mathieu Turi and stylish and sleek cinematography from Alain Duplantier. Contrary to its title, film does not meander at all and is lean and concise.
