I like both, they're both extremely different when you think about it, both in terms of character development and presence. Goode had a bit more of a weasly quality to him, but the whole 'smartest man alive' deal came across quite well in the film. We get to see him tell off several people and make a good deal of 'convincing' arguments.
The scene with big automobile and energy barons made Ozy seem much more like a superhero who simply works on the inside now and uses his power and money to leverage against those that simply seek the rate of return. I thought that entire scene was very well played and probably threw off the GA.
By the end however, his insanity is really pretty apparent. "I made myself feel every death..." Well at least to me that seemed terribly disingenuous....especially following everything that happens before. When he murders his entire crew, that scene just oozed evil.
Also, there was a lot of more altered dialogue towards the end between the rest of the crew and Ozy. He seemed much more sinister in part due to the dialogue as well as Goode's appearance and acting.
One thing I missed was....well I can't quote it verbatim but Ozy looks at Manhattan towards the end and says something along the lines of "I did the right thing....didn't I?"
I felt like in the comic, Ozy's own self-doubt was registered a bit better, but in fact, the shot of Ozy standing there, holding the wound in his hand surrounded by shattered glass...well I think that conveyed that sentiment without words quite well.
Also, I have to check the comic again, but when Ozy just takes all of Nite Owl's blows...well I thought that was done really well. You get a sense that he is truly dedicated to this idea, almost to the point of a sort of insanity. I thought it almost paralleled Batman and Joker in the interrogation room. Joker just takes it because his 'cause' is deeper than his own existence, just as Ozy feels about himself, albeit in a different philosophical context.
