Slow, highly circumstantial, uninteresting character development and very predictable sequences, over and over again. Sam Neill was such a tease, to then kill him off almost immediately. Quite shameful overselling of big actor to get early traction.
(Spoiler alert) I am truely amazed how the UK kids managed to cross the Channel Tunnel, and the french security just let them wander off, and then they travelled another 250 miles to Paris without any issue.
I am watching because I am a sucker for sci-fi and like the alien elements/mystery, but overall I would not recommend unless you are willing to sit through a lot of mundane content, for some big, off world ideas.
