Home: Taken
I would like to see the Bryan Mills character again, doesn't need to be another kidnap plot, could just name it something else like they did with U.S. Marshals. He calls himself a 'preventer' in Taken, that to me would be a good title. It could also include his former agency buddies too.
Oh... after a quick look on google seems they are making another one. Still like the 'The Preventer' as a title, 'Taken 2' just sounds unnecessary as another kidnap plot won't be as good.
