Pulp Sci-Fi Theater

I came up with this idea about a year and a half ago. It was just a quick little flash of inspiration I came up with in about 5 minutes of boring Spanish Class. I had no illusions that it was anything special, but thought I'd go ahead and jot it down just as an entertaining plot idea. One of my friends thought I was being a bit more serious than I was and promptly tore it to pieces, pointing out all of it's many cliches and logical inconsistencies, which I found amusing. Looking back at it, I agree it's nothing special, but I think with a bit of polish and a nice animation budget, it could be turned into a pretty cool action movie. Nothing all that intelligent or thought inspiring, but a nice action movie at least. I do think it's somewhat unique in that it's a Giant Robot Anime with only a single pair of Giant Robots; most of the combat is against conventional weaponry like jets, tanks, and ships. Here it is:

The year is 2035. Technology hasn't advanced all that much, but history is repeating itself as America and her allies face off with The Russian-Chinese Union in a Nuclear standoff, with the possibility of worldwide destruction a daily threat.
Out of nowhere, a giant humanoid robot (a la Gundam) appears and attacks a Russian missile base, killing thousands and destroying the base. Equipped with extremely advanced technology, the Robot can magnetically deflect any missile attack, move freely between land, sea, and air, and can reach speeds inaccessible by any modern aircraft. The Russian Air Force pursues the Robot, but it retreats to the east, into American air space. The Union quickly blames the U.S. for the attack, but the American President assures them they are not responsible and will shoot down the unknown bogey immediately.
Off the coast of Alaska, the Robot encounters an American fleet and swarm of aircraft. They are dealt heavy damage, and the Robot flees up through the atmosphere directly into space, crashing into a spy satellite and sending it crashing down into the ocean. From around the dark side of the moon, an unknown spacecraft approaches and begins repairing and rearming the Robot.
On the surface, the U.S. and Union call for a halt of hostilities and focus on the unknown enemy. Russian scientists work on researching the damaged pieces of the Robot recovered, while America works on the building of massive rail guns for attacking the Robot as it reenters the atmosphere. After thirty two hours, the Robot dives back down into the atmosphere, dodging the rail guns as it enters. It returns down to the sea and captures an aircraft carrier. It takes the crew hostage, and, using text-only transmissions, orders the crew to transport it to Japan. The Americans, hoping for time to develop a method of countering the Robot, agree, and battle ceases as the carrier sails for Japan.
Arriving at Japan, the Robot enters Tokyo and transmits to the country. Revealing himself for the first time is pilot Nataku Yamato, of 1/2 Japanese, 1/4 Korean, and 1/4 Nigerian descent. He requests Japanese citizenship and sanctuary from the Superpowers in exchange for military and technological assistance, on condition that if he is killed or his machine taken their country will be destroyed by his "allies". He gives the Japanese two hours to respond. While the Japanese debate, the American President and leaders of the Russian-Chinese Union meet in secret on board a battleship in the pacific.
Japan agrees to Nataku's terms and he exits his craft and meets with the leaders of Japan, giving them computer data to make extremely advanced technology including Alternate Energy Reactors. Shortly thereafter, America and the Union declare war on Japan.
Cut to 6 months later.
The Superpowers are at war with Japan, which is backed by a vast number of minor countries throughout the world, having given support in exchange for the Alternate Energy Reactors. Battle rages back and forth, encompassing the entirety of the world. The world is shocked as another Humanoid Robot appears and attacks the Japanese force and Nataku's machine. He is saved only by the use of the Temporal Disrupters within his machine, capable of bending time and space around itself. The new machine appears in Nigeria and aligns itself with Africa and the Superpowers.
Cut to 6 months later.
The war has reached the heartland of Africa, and as battles rage all around the two pilots duel with their machines on the plains of the African Savanah. As they battle with their Temporal Disruptors, a portal storm appears in the sky overhead and devastates the area. Both machines are damaged to the point of being inoperative. Nataku drags himself out of the machine and across the field to his enemy. He tries his own access code on the cockpit and is surprised to find that it works. Inside, he comes face to face with a pilot that looks exactly like himself. They both draw guns and fire, killing each other.

Cut to 20 years later.

The war is over, both sides having halted once the instigators of the war were dead. The Temporal Storm over Africa eventually transformed the bulk of the continent into an agricultural Eden capable of feeding 3/4 of the worlds population. Throughout the world, Alternate Energy Reactors are now common place. In the middle east, a 14 year cease fire continues as the Oil rich countries try to deal with the loss of their wealth. Despite these losses, the standard of living for the average people in these countries is increased as Alternate Energy is now available. The Union and American allies have ended hostilities, and a new era of scientific discovery has begun as the remains of the future machines are studied. In Africa, the bodies of the two Nataku's are displayed publicly at the Tomb of Two. Some call them terrorists. Some call them warmongers. Others call them saviors. No matter what the opinion, their name is known to all the people of the world.

Cut to Post Apocalyptic wasteland, where a small city in a dome is struggling to survive. A scientist, who appears to be Natakus father, considers the risk he has taken in sending his son back to try and change the past, not subtly, but with a hammer strike. Knowing nothing other than his son is now dead, he returns to his life of waiting for humanity to die.

Gainax WTF endings FTW.

So, would you go see it?
