The film should start off with the explosion of Krypton and the ship making it's way to Earth. Similar to SR's explosion.
Then it should say something like "30 years later" and it goes to Clark getting to Metropolis and it's his first day at the Planet. This is where we're introduced to Lois as he tells her about Smallvile and the Farm, nothing too detailed though.
Then, not long after, an accident happens and it's Superman's first appearence rescuing Lois.
This then leads into Lois' interview with him where we're told about Krypton etc, all shown in flashbacks and not like "Can you read my mind". These flashbacks are very basic...Jor-El knows about the state of the Red Sun, the Council ignores him, he puts Kal-El in the pod.
Then, later on, Brainiac turns up and during the fights he tells Superman (and the audience) more details about what actualy happened on Krypton.
This way, we get an origin, but without being bogged down with too much Krypton and Smallville. We don't really need to see ALL of that stuff, just enough to fill in the 'blanks'.
