He Sees You When You're Sleeping. He Knows When Yo
The Overlord said:Frankly I don't like your idea, Brainiac should be sinister, he should have destroyed numerous worlds before comming to Earth, he shouldn't be confused and is trying to destroy Earth by mistake. He should destroy Earth because he is sinister not confused and green skin would look stupid on the screen.
You know what I have liked this Luthor, if his scheme made sense and wasn't recyled from the first movie, that didn't make him seem very clever.
A "Sinister" Brainiac would be more stupid than Funny Happy Brainiac.
Brainiac has no emotions, period. He holds no grudges, his programming is to record a planet's culture and information, and then destroy it, so that his information is complete... Leaving a civilization be means that it will progress, and the information will not be up to date. That is why he would destroy a world.
Not because he's "Sinister"
And I'm not going to concede about the green skin, because if they wanted it to work, they definitely could. The artificial skin could just be an off color, giving it a eerie green look. He had the green artificial skin in the Animated Series, they just toned it down to make it look less vibrant.
This Look wouldn't work in live action, though. No matter what you say... It'd look like a halloween costume gone wrong
It'll probably end up being some variation on either of the two Pre-Crisis brainiac... The silver robot Skull version, or the Green skin version with the Brainiac diodes on his head.
I'm going to stop adressing your problems with Luthor, cuz I disagree that he was portrayed badly... I do think that the plot got a little conveluted, but in the end, It didn't take away from how much I liked the film. And it certainly didn't change the fact that I feel that Spacey did an excellent job as Luthor.
Also: Grammar is key.
