I've been meaning to watch this show for a while, and for some reason (maybe because I'm feeling a bit ill) I just decided to start watching it... and I like it!
The premise is very similar to Twelve Monkeys, with people from a nightmare desolation future being sent back in time to put things right in small ways. It also reminds me of Dead Like Me, given that the new travelers take over the bodies of the about-to-be-deceased and have to take over those lives afterwards. It also reminds me of Odyssey Five, but I was never able to get into that show. There's even a bit of Person Of Interest in there as well. The fact that it reminds me of these other shows isn't a point against the show at all, it's a simple premise that works quite well. One of the producers of the Stargate series made this, which is great because the Stargate guys also made Dark Matter (which I love) and Blindspot (which I haven't seen yet but I've heard is excellent).
And the show is episodic, which is great. I love a good episode series, especially since this was made direct for Netflix. It feels like I'm watching a proper show instead of one written for the trades. It's TV-MA but doesn't scream that in your face (no gratuitous nudity or sex, just a couple curse words in there).
...that's all I have to say about it thus far. Like the show, like watching the show, like the characters, premise, good writing, there's one or two "oh sh*t" moments in each episode, which is a plus, and it's made in Canada so quite a few familiar character actor faces. If you have the means, check it out.
