Ehh...no. At least not from this trailer. Ashton eerily kind of looks the part, but his performance felt a bit forced even in those split seconds. On top of that; Untested stary eyed misfits playing in the big leagues, main character spouting optimistic exposition, shouting in a phone, and venting in his car, quirky music that becomes dramatic and tense then changes to uplifting. This is what we call boiler-plate.
Who knows, The Social Network looked like a generic "Optimistic Genius Rebel VS. The System" movie, and it turned out to be really, really good and ultimately a story about characters, their relationships, and the means and actions they take to pursue their goals and the consequences of those actions, instead of just being another "inspiring" underdog story.
Wow, I so don't care about watching Ashton Kutcher play Steve Jobs. If you want a good look at early Apple then watch the old interviews. Steve Jobs as, Steve Jobs is really amazing and this is coming from a PC guy.
