I have the complete Final Crisis run with all the tie ins on my tablet. Starting at Countdown 27, all the way through Countdown to Final Crisis 26, to DC Universe Zero, Death of the New Gods, Faces of Evil, Final Crisis, Aftermath, Origins and Omens, and Rage of the Red Lanterns. What can I skip out on here? This is wayyy too much shit to go through.
Skip everthing that is not written by Morrison, those stories DO NOT enhance FC but contradict it in many ways and show that Morrison oder DC editorial did not share what the story was about with anyone else or DC ignored what Morrison proposed because the tie ins DO NOT FIT IN AND WILL IMPACT YOUR ENJOYMENT OF THE STORY!
Countdown is a bad fanfic that abandons it's premise and storylines quite fast, and even it's more important pieces were never picked up later on.
Death of the New Gods is an okay read but has nothing to do with FC, or the bit that is imporatant is presented in an entirley different way.
Origin and Omes, as well as Faces of Evil were a big mess, promising important story threads that led to - exactly - nowhere.
Rage of the Red Lanters is simply a GL storyline which would works without any connection to FC.
What you need to read is:
FC 1-7
FC Submit
Superman Beyond 1-2
And the two Batman Tie in issues written by Morrison.
It flows best in my opinion when you read it in the following order:
FC 1-3, Superman Beyond, FC 4, Submit, FC 5, Batman Tie-ins, FC 6 & 7.
