Giving the fan a relaxed episode for once, "It's Not a Rumor" has the crew helping to distribute the vaccine and making contact with people all around the USA and Europe to help things start working again. At the same time, long forgotten and last seen on the Russian ship Niels... well, he's back (and it seems being alone has made him crazier than ever). And there seems to be a new threat in the horizon...
The episode gives a lot of time to the crew, to let the viewer connect with them and see their inner struggles as they reconnect (or try to) with their lives and their loved ones that have survived the pandemic. It is all already threaded territory, seen a million times, with not a shred of originality, but it does a good job in making us see the characters as people (even if the character's development is cartoonish as they come; excerpt number 1: Chandler goes back home and the first thing he does is put the flag back up; just in case we didn't know he felt a patriot). The show is also falling a little bit in Chandler-as-god (whatever references to Noah and his ark, it is clear he is more of a Jesus) which diminishes somewhat everyone else in the series. And we got some more of those the army-is-our-family speeches. Subtlety is not a word the writers of the show know.
However, it is all interesting, the new threat seems a different one from our globetrotting adventures with your bad guys from abroad that was so popular in season 1 (yes, Niels apart) and the actors make all engaging enough.
