I got so many questions. Please help!

I''ll try to give as concise answers as I can. For reference, all my answers come from information given in the film, I have not read the manga.

1, b, c, d). Akira was a telepath/telekinetic (obviously the powers were actually way beyond those terms), and was the same age as the "blue kids" in the film. He was the most powerful of the group and had extensive experimentation conducted on him. As such, he eventually lost control of his abilities and causes the explosion seen in the opening of the film, and dies afterwards. The military scientists dismembered, and perserved his tissues for future research. Regular people view him as a deity (his powers are god like after all) and from this become zealots awaiting his "resurrection".

2, b, c) Most of these are answered in question 1 except for 'c'. Most movies have plot conveniences, the obvious parallel in this film is the bombings of Hiroshima and Nagasaki that are generally regarded as the end of WW2.

3, b) The scientists were trying to understand their powers and how they operated. It's established that it's a dormant ability people could "unlock" through some means. In the film, Tetsuo had his awakened when he comes in close contact with one of the "blue kids". If the military could learn to unlock, and control these powers, their nation would become the supreme military power.

4, b, c) Their objective was to rescue the "blue kids" who have been medical experiments for over 30 years. They don't think this type of power should be wielded at all, let alone politically. They were in league with the politician to gain information, and access they otherwise could not get.

5, b, c). Those waves are from an instrument that has the ability to read, or measure telepathic powers. The audience is given no info on how it works, it's a product of the story's universe. The Colonol gets mad at the scientist because earlier in the film he tells the scientist to kill Tetsuo if his powers get out of control. The scientist however, was too fascinated by the events and did not stop Tetsuo when his powers got out of control. The Colonol chastises him when he realizes what has happened.

6) He's the runt of the pack, and a loner. He's shown to be moved around a lot as a kid in foster care. All that, coupled with him being reserved made him an easy target. That's just how life is sometimes.

7) I'm not sure I fully understand the question. Kaneda taunts Tetsuo because at that point in the story Tetsuo is flaunting his power over Kaneda. He doesn't need Kanda to protect him anymore (we see in the flashback that this has been happening since they were children) and wants to show off how all powerful he is. Kaneda taunts during the fight to not give Tetsuo that satisfaction. He's goading him into a mistake he can take advantage of during their fight. Hope that's what you were looking for.

The thing about Akira is that you really can't fully appreciate it in one viewing. The first time I viewed Akira I did not like it as well. After a few watches the answers all came out and now it's one of my favourites.

Obviously I'd recommend watching the film again and see if you enjoy it more now!
