I stand corrected. He's completely flamboyant.

I don't know, though. I love Barrowman, but I think he's sort of the UK tv-whore. He's on everything, from what I understand, always pimping himself out as a television personality. Meanwhile, I find that I enjoyed his Captain Jack character during his first appearances (Eccleston season). After that, he's seemed to get campier and less serious. Captain Jack himself should be pretty funny and laid back, naturally. That's what makes him a great character. However, compare the guy who stood down Daleks in Parting of the Ways with the guy who cheesed-out the line "Like I was sayin'....feel this!"{shoots Dalek} in Journey's End. He sacrifices any gravitas he has when he tries to be "cool" or "witty". I'd rather just see him be casual and care-free, but still get serious and kick some ass when it calls for it.

Also, Captain Jack on Torchwood is just the opposite end of the spectrum. Too morose.

Maybe that's just me...
