This is sad news. I like J.J. (aka AJ Cook). Criminal Minds' FBI BAU Supervisory Special Agent Jennifer "JJ" Jareau will not join the rest of the team in the upcoming sixth season.
The show's producers did not renew AJ Cook's contract due to 'creative reasons.' I'm not sure what it exactly mean but the change is not really needed. After all, they have solid, consistently high ratings. I am also thinking that the decision probably has something to do with the spin-off. I hope the replacement will fit the cast and fill the void.
Another character who is also being affected by the network's creative decision is FBI BAU Supervisory Special Agent Emily Prentiss (placed by Paget Brewster). She will be appearing in a reduced number of episodes.
I don't really understand but these two female characters are well-loved in the show. They're smart, independent and acting-wise, they're kick-ass.
And if ever they remove my beloved Supervisory Special Agent/Unit Chief Aaron "Hotch" Hotchner from the show, I'm gonna scream!
