Steven Spielberg. Halle Berry. A robot son and an unborn half human/half alien baby. Got your attention yet? Good, because if you're looking to add a new TV series to your viewing schedule, Amazon hopes you'll choose to watch its latest original. It's called Extant and it revolves around an astronaut (played by Berry) who returns home to her family from a year-long solitary space mission with a new life inside of her. All that we know is that her experiences "will change the course of human history." Could the baby have something to do with it? Possibly. The 13-episode first season is executive produced by Spielberg and is available on Amazon Instant Video each week a day after it airs on CBS in the US. After checking out the premiere episode, we liked the overall plot and reckon it offers enough mystery and tension to keep us watching (even if it starts a little slow). If you have a Prime subscription, then you'll be able to stream Extant right now via the web or on your smartphone, tablet or console.
