I suggest you go back and watch it, he wasn't trying to kill the world leaders but mutate them so they would have to be more tolerant to mutants.
Was he though? If you want to argue that Magneto was the main villain in FC and X2, I could just as easily make a case that Pheonix was the main villain in X3. She did the most damage in the movie and was the big weapon all at the same time.
He pretty much was.
I wouldn't say it was the exact same personally. For example, he turned much sooner in DOFP than he did in X2.

Him turning against them sooner doesn't negate anything. Sinner or not is not the point. I'm sure you're aware of this. Machine created to be used against mutants ends up in Magnetos hands and he uses it against the humans. Its more or less the same. He did it with Strykers cerebro in X-2 and Trasks sentinels in DofP.
So because people criticise other franchises for it, that means you have to attack this franchise to make up for it? Sorry that doesn't make sense. Plus in FC, X2 and DOFP he wasn't the main villain, other people were, so in those movies it didn't get repetitive to me. It's only right at the end he does something villainous, the likes of Shaw, Stryker and Trask did evil things throughout, yet somehow people claim Magneto was he main villain in those movies when he clearly wasn't. That's why it isn't repetitive to me as we have had other villain along the way.
How am I attacking this franchise? You're making it sound as if I'm being hostile? I'm no the only one who feels strongly about this. There have been people here who feel the same but I'm just more vocal about it. Let me break it down for you.
X1: Main villain
X-2: Works with the X-Men and Turns against them
X-3: Main villain
FC: Works with the X-Men and turns against them.
DofP: Works with the X-Men and turns against them.
That is my point^^ Notice a pattern here? That's why I'm saying its repetitive.
It's been done over and over by Apocalypse in the comics though, not Ultron, how you can criticise this movie for giving its villain comic accurate motivations and then praise AOU for not being accurate in its villain depiction? It smacks of hypocrisy to me.
*sigh* I didn't criticize anything. All I said is that his motives sound too similar to what Ultron was trying to do. That is all. I didn't praise AoU at all in this thread.

A couple pages ago I even said :
I just hope Singer does a better job at exploring Apocalypses motives than Whedon did for Ultron. Took me a couple viewings to understand what Ultron was trying to achieve in AoU.
I drew similarities between the two villains.In fact when the trailer for Apocalypse first came out, I said I hope Apocalypse isn't just a "haha I'm gonna deatroy the world" villain (judging from his speech in the trailer) and actually a poster or two here responded saying his motives won't be that straight forward.
Not once in the comics have I read an Ultron story where he thinks he is mankinds saviour and wants us to evolve, but because the MCU did it's suddenly okay. But how dare an X-Men movie do it!
Where did I ever say it's okay for the MCU to do it and how dare the X-Men do it? I didn't even insinuate that. I just said its been done over and over again that when Apocalypse does do it, it won't be too different from what we've already seen from Ultron. But now you wanna make it a MCU vs X-Men debate when it wasn't even about that if you read my previous posts and what I was trying to say, yeesh. We're done here.
