Very curious, this one. I like the fact the writers seem to be taking risks this year. They're not trying to do a million different stories at once, but are still keeping the show pacey. WTLV is a neat example of that. It's the kind of great premise that would make a cracking film.
I loved the car showroom shootout, that was extremely clever; I loved the whole idea of Jack meeting the man who trained Irina for her marriage to him (and maybe the idea she too was trained as what became known as Liberty Village back in the day); loved them bringing back the KGB encoded order books from season one; I like how Nadia/Weiss is going. My only concern is that it all feels a little rushed, especially the APO scenes. It's almost like the director is telling Ron Rifkin to get his lines out as quickly as possible. Apart from that, I thought this was a good ep.
And as for 'Sentinel'. Hmmm, why would the Russians, why would Jack & Sloane, be looking for Yelena Derevko?...what odds are you giving that it has something to do with a certain 15th century genius?...
