OSP and Red team continue pursuing an elusive, unknown killer as the body count rises.
Part Two had more moments between Callen and Paris and the members of Red team, Scott Grimes bringing the comic relief. I don't get the sense that a Red series will be very different from NCIS: Los Angeles, but if Part Two's ratings hold up to Part One's, CBS could make a full night of NCIS, with Red in the Tuesday 10:00 P.M. slot that has lagged for years.
If Red doesn't go to series, I'd welcome Paris or Red team back on either NCIS or NCIS: Los Angeles.
UPDATE (May 15, 2013): CBS decided against bringing Red to series. The ratings were decent, but apparently the concept wasn't strong enough to sway execs. Instead of a full NCIS night, CBS is moving Person of Interest into the Tuesday 10:00 P.M. slot, so TV's three most watched dramas will air on the same night.
