Just saw this for the first time and was very impressed. So as not to repeat the praise everyone else has heaped on it (which I by and large agree with, I must say the lack of plot flaws was amazing for a fifties sci-fi movie. Characters actually act and make decisions in a recognizable way, not with sci-fi movie logic. During the montage where the Earth's power is disrupted I couldn't help but think "No death!? But what about all the hospitals and people relying on machines to keep them alive" but it was explained in an internally consistent way instead of ignored. One complaint though. Flying saucer in the middle of DC, dangerous robot, tons of spectators, and a hunted alien who might be trying to get back to the ship. And the Army only posts TWO GUARDS at night. Riiiight..... Still, I'll give them that one for free.
