Complete waste of time. First three or four episodes drone on with nary a view of the invading aliens. Then these small creature supposedly wreak complete destruction on the biggest cities of the world? Then, at the last minute of the last episode, suddenly the aliens are instantly totally defeated, show over??? Really? Sprinkled throughout the episodes are truly inane scenes showing that the writers are completely ignorant of science and physics (a space-suited astronaut, completely adrift, “swims” to a nearby space station using only her arms.) Come on!
