I think it's a terrible idea in general. Costello, French, Costigan, Sullivan, Brown, Barrigan, and Queenan are all dead. Meaning every important character other than Dignam is dead. A sequel wouldn't work, but I could see a prequel. I see a title like "The Departed II: The Rise of Costello".
I agree. I don't think a sequel would work but a prequel good. In any case, I don't think it'd be directed by Marty so it would already be starting off on the wrong foot.
