"A bit I can’t seem to get past is my strong belief that, while Capt. Jack is a great character, he is not a great central character. Jack works incredibly well as a member of the TARDIS crew but as the leader of this incredibly messed up clandestine organization, he doesn’t compel.
[…] As I said earlier, he’s the Han Solo of the series. A Han Solo TV show would be excellent if he were out smuggling and pirating it up on the Millennium Falcon, but how boring would it be if the show were Han Solo training new recruits or running a fleet? Capt. Jack Harkness only really works as a supporting character, despite how cool you may think he is. He works in Doctor Who remarkably well, and he works just as well in “Children of Earth” because he’s no longer in charge. Hopefully, for the new series, they’ll keep his character roguish and not give him too much responsibility.
