2016 SF, 13 episodes. The plague that wiped out human civilisation is
still a problem for the post-apocalyptic time travellers to solve, but
other time travellers are a greater threat.
There's been an interesting shift in emphasis with this season,
spending rather more time in the future with Dr Jones and the time
machine. Cole and Railly are still the field agents, of course, and
their ongoing personal plot is most often that one of them wants to
carry on with the mission at any cost, while the other looks at the
damage they've already done and wonders whether it wouldn't be better
to give up. By the final episode they're more or less synchronised:
and indeed there's a point about half-way through that final episode
which could easily have led into an ending for the whole series, if
the show hadn't been renewed again.
The supporting cast from season 1 is moved mostly to the background
(particularly Kirk Acevedo as José Ramse, who has much less to do this
time), and rather more time is given to Dr Jones (still Barbara
Sukowa, and still the best thing in the show). One could make a good
case that she's the real protagonist of this series: it's essentially
because of her actions that everything else happens. The really
surprisingly good actor here, though, is Emily Hampshire as Jennifer
Goines: in season 1 she was mostly a generic loony opposed to the good
guys, but here she brings remarkable depth to what has become a very
Time travel is a big part of this, and while it's not a complete
free-for-all it's definitely become rather looser than season 1
allowed. While it's never exactly light-hearted, the show allows
itself to have fun with paradoxes. There's rather more historical
material than before, with extended sequences in the 1940s and 1950s.
This isn't lightweight viewing, but it repays attention, and there's a
sense of engagement and progress that's rare in modern television. The
show has been renewed for a ten-episode third season.
