Seriously?
Nero and Soran had the same motivation.
Yes but the writers at least attempted to give some depth to his loss and why he wanted to return to the Nexus. I could understand that and relate to the character. Nero, on the otherhand, I could have cared less about because he was a Threat[TM] and an action figure with no depth.
Nobody but Picard, Data, Soran & Guinan had a part in Generations......and Guinan isn't even a main cast member.
But they at least had some depth in those scenes. There was emotion. Picard's loss wasn't just treated as one of a thousand plot points. It actually resonated and tied into greater themes. The writers stopped and made me feel and think.
Amanda's death, Vulcan's destruction were there for the big bang not any relevant emotional payoff or reflection. It didn't move me or stun me beyond the actual boldness of the idea itself. That is what elevates GEN over XI in that regard.
And I could care less if Abrams used Nemo and literary sources to guide his influence on Nero. You couldn't tell from the shallow characterization.
