Not the final fight with 4 banshees and a reaper shooting lasers at you?

This part I even had problems on normal. 

This part is very simple only. You are not required to kill all or any. Just take cover and wait for EDI to give the green light then run to the control panel once hammer weapon system syncs with normandy.

like that oso hard, since banshee will come and kill you   

Not the final fight with 4 banshees and a reaper shooting lasers at you?

This one you only need to watch your distance. Once the truck is online. Quickly run and press the button. No need waste time shooting.
Edit: Your choice for partners also matter imo. Bring partners who can lob grenades. James (frag grenade) or Javik (lift grenade). Can buy you some time to shoot while they flinch.
Biotic combination also will do; Liara and Javik. Dark Channel + Warp = sexplosion. I brought these two.

The Kai Leng part was hard because the tight room. In insanity enemy keep spamming grenades. One hit kill.

The Matrix and Spider-Man was alright to me. The endings fit what the movies were. Though maybe I should watch them again, I watched Matrix when I was a kid and last time it was all, "Explosion! Yay!"

The difference here is you are comparing movies to games. In games, the endings CAN be patched, they can be changed if the developers see a better way to end them. I can't say anything about Star Wars since I haven't watched the initial trilogy recently. And wtf Romeo & Juliet? ME3 was never a love story was it? I can't say I've read Romeo & Juliet so I can't give any more in-depth analysis of the story but seriously, comparing ME to Romeo & Juliet is just nonsense.

And just to answer your initial statement, there is no expectation that ME3 would be a true masterpiece. The thing I said was that ME3 would be a masterpiece if the indoctrination theory were true. Please don't just read a single sentence and throw the rest of my post out the window. There was however an expectation of more than 1 ending with 3 slight differences between them. The developers have always said that the endings would weigh in all your choices from the previous games. That was why you were given the option to import your save files. If in the end, no matter what you did, you'd separate all the races of Mass Effect by destroying all the mass relays then what the hell was the entire of mass effect's plot for? Throughout the whole of ME3, you go uniting all the races. The Turians and the Krogans, the Quarians and the Geth. What was that for? Just to build an army strong enough to get on the crucible? Mass Effect was more than a war against the Reapers, it was Shepard's effect on the galaxy. This human race, an infant of galactic travel, uniting the races to bring about a common cause: Survival through any means. And if that means is the destruction of the Reapers then so be it.

You know, there's a reason they let you unite the Geth and Quarian last. They want that choice to still be in your head when you make the choices at the ending. Knowing that you've united the Geth and Quarian before, why would you choose to destroy? You have single-handedly caused and experienced the unification of an organic and a synthetic race. That Shepard would not argue against the holographic synthetic God starchild is just nonsense. On the brink of death, a God appears before you and tells you that you can throw all you have accomplished away, control what you have sought to destroy and right after you just told TIM that you can't control them, you have to destroy them or unite all synthetic and organic life <- What Reapers have been doing, serving you plates of bio-synthetic death machines made from organics harvested throughout the galaxy.

Sorry, I got sidetracked but to just accept the ending of Mass Effect is like you haven't played the previous games at all. People aren't pissed because they want this game to be god damn bloody brilliant, they are pissed because all of their actions in the games culminates in a select screen at the end. And initially, my post was to incite discussion on the indoctrination theory and suddenly some people take parts of my post out of context and start a pointless argument.

Good read, it is essentially a very well detailed explanation of why the indoctrination theory is true.

The journey you undertake in Mass Effect provokes an intense range of highly personal emotions in the player; even so, the passionate reaction of some of our most loyal players to the current endings in Mass Effect 3 is something that has genuinely surprised us.
