A modest but intelligent and extremely effective adaptation of John Wyndham's novel The Midwich Cuckoos, about a small English village which mysteriously and inexplicably succumbs to a 24-hour trance-like sleep, after which the womenfolk all discover that they are pregnant. The alien children, strangely alike in appearance, prove to be endowed with telepathic and kinetic powers...You don't get much explanation, and the overall plot may not withstand detailed analysis. But the atmosphere and pace are superbly handled, and the performances of the sinister, inhumanly intelligent 'children' never falter. The allegorical possibilities (generation gap?) are there, but they don't get in the way.
