SOMA is good and you should play it. You shouldn't watch the first video in this live-action video series if you haven't already played it, though. So go away and play it first, yeah?
You're back? Good.
It's not that the video really spoils anything, but SOMA deserves to be played through completely fresh, and with an open mind. PATHOS-II is derelict and haunting - you find out what it was like before your arrival through environmental storytelling and audio logs.
