Re: 5 things you want to see
Ultron being Ultron
More Hulk personality and relation to Thor like in EMH.
IM returning with AC/DC
And most importantly. I want an truly epic fight in the end with epic freking music. I want the feeling when Rohan is about to attack Minas Tirith. Maybe you could fit in the "Ultron, we would have words with thee" thing there.
