I'll tell you : because I'm interested in the plot involving Callen's identity and I love Linda Hunt (Hetty).
It's not for those kind of episode : the bad guy was a Muslim (as usual), he was a foreigner ( as usual) and the guy who drove like a madman had an accent which immediately indicated he was a foreigner thus a bad guy ; and worse, he was a Muslim !!!! Funnier than all, as Callen doesn't speak arabic but russian, the bad guy was a Muslim Chechen. As if the Chechen had nothing to do in their country but be involved in guess what ? Al Qualida of course ! The only muslim terrorist organization the writers of this cr*py show seem to know because they do as much research on terrorist organizations before writing an episode as me before watching a soccer game !
Fed up with watching xenophobic s...... When they get back on Callen's identity, I'll come back. For now, I'm gonna watch a great intelligent show about terrorists and spying : Homeland.
