I'm sure the movie is terrible (I've read the contemporaneous books, though not Mitnick's more recent one), as you might expect from a Hollywood crime story.

But what's Mitnick's side of this story supposed to be? The crimes he was sentenced for got his co-conspirator probation, right? It seems pretty clear that Mitnick mostly got punished for being a recidivist. Even Mitnick doesn't claim to be innocent of the charges; in fact, he's spent the last 10 years trading on his criminal reputation.
