I have just watched episode three from season four - so the latest one.

Spoiler Alert, click show to read: 
Certainly the best in the latest season (for now of course) - I was totally 'hijacked' the chief's wife pushed to the limits of her sanity.
I enjoy military episodes a lot ( 33, Pegasus, Resurrection Ship etc), but the psychological-political drama in this episode is really something.


Season four seems to promise a lot indeed, let's hope it will continue this way.
