Overall, nice, but I think Ultron went about it the wrong way.

Rating: 8/10 (5 May 2015)

Spoilers: Personally, I like the movie myself. However, this is a minor thought, and I could be wrong, but raising a city that high then flinging it down, even with rockets, does not seem to be enough to create an Extinction Level Event. I think an asteroid, a mere 1.5 kilometers in width, brought down from space at 45,000 kph will have enough kinetic energy to lay waste to mankind. Not as spectacular nor as cinematic as Ultron's "raising a city", and there's no chance for the Avengers to waste their time saving civilians, but it's a sure thing. In Gurren Lagann, (one of my favorite anime now) the Anti-Spirals planned to send the moon down to earth. That's a 3,500 km in diameter sphere from a distance of 365,000 km away. And this will spiral in, remember, not just bump the earth like in billiards, so the tidal effects will lay waste to the earth's surface before it enters our atmosphere. I like the numbers in that. http://en.wikipedia.org/wiki/Gurren_Lagann
