This England is an excellent dramatic series, perhaps too close, that portrays a very difficult period of time not only for England but for the whole world, in which some governments were incompetent, they did not know how to face the pandemic.
Being honest I have to admit that I watched the series to see Kenneth Branagh work, it's fascinating how he gets the voice, the gestures, the physicality, he becomes Boris, but what makes his performance perfect is that he doesn't judge the character, he doesn't ridicules not condemns him, Branagh shows Boris for the viewer to judge. The rest of the cast and crew also do a great job. It's worth the time, sometimes a little hard to watch but it's important not to forget what happened and where everyone was.
