I just watched it and Kutcher shouldn't have been cast
This isn't saying Kutcher didn't do a good job. He did a great job but for Ashton Kutcher. His best is probably Christian Bale's worst. Christian Bale as Jobs would have been great.
Also, the script was bad. Pirates of Silicon Valley was just a better script. It was like watching the movie 21 instead of a biography of Steve Jobs.
For instance, when Jobs opened the letter from Lisa and then later in the movie she's sleep on his couch. This was just poor writing. There should have been a scene connecting the two. After he gets the letter from Lisa, you then have a scene showing Lisa's first visit to Steve's house and he goes to shake her hand and she gives him a hug. You then show Lisa sleeping on the couch in the later scene.
The movie had several scenes like this where the writers didn't connect the scenes.
Favorite movie of all time - SCARFACE
