This 10-episode first season starts out with some great sci-fi premises: Earth destroyed by sectarian warfare, a remnant of humanity escaping to exoplanet Kepler 22b (an actual planet that may be able to support life), strange life forms (some extinct, some not so much), and the nature of androids. Some nice twists along the way, and thought-provoking plot developments. That's the first five episodes.
The last half of the season devolves into mind-tripping, psychological flim-flammery, unbelievable leaps forward in storyline, and a season finale that has to be seen to be utterly disbelieved. So much that is ridiculous and inexplicable happens in the last 55 minutes that all the hard work that looked to pay off in the early shows goes completely down the toilet -- or one of the many literally bottomless pits that seem to dot the landscape. The biggest waste of time is by the actors, who put so much of themselves into their characters. Watch this show if you must, but only to honour their work. The screenwriters and director(s) can hang their heads in shame.
