Always been a bigger Marvel fan, but recently I have become interested in DC with all the talk of a DC Cinematic Universe and this is how I think it should go:
Phase 1
Man of Steel
The Amazon/ian
The Batman/Gotham's Knight/The Dark Crusader
The Emerald Knight/Soldier (reboot)
World's Finest
Justice League
Phase 2
Man of Steel 2
The Amazon/ian 2
The Emerald Knight/Soldier 2 (reboot)
King of the Seas
The Manhunter
The Flash
New Gods
Justice League 2
Phase 3
Man of Steel 3
The Amazon/ian 3
The Emerald Knight/Soldier: Blackest Night
King of the Seas 2
The Flash 2
The Batman/Gotham's Knight/The Dark Crusader 2
War of the New Gods
Phase 4
Justice League 3 PART 1
Justice League 3 PART 2
Justice League 3 PART 3
Now, I would like spin-offs after the main series, such as "Green Arrow", "Black Canary", etc. Also, I believe they should at least build up their villains in previous movies like Marvel and have their own version of SHIELD. I will go into detail on the individual phases on later editorials. For now, lemme know what you think of this and how you want it to go.
