Bumpy Chip It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

Brenda The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

Lela The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

Logan By the time the dramatic fireworks start popping off, each one feels earned.

amirams It's a shame that the History Channel presents a theory that was postulated some 25 years ago but has since been proved wrong or at least unnecessary by most scientists, without even mentioning that this theory is outdated and mostly abandoned.To begin with, the theory was based on a hypothesis that mass extinctions occur on regular 26-million year intervals. This is no longer believed to be true. In addition, recent analysis of data on outer solar system object orbital patterns suggest that Nemesis couldn't possibly exist. And several detailed astronomical surveys that should have detected Nemesis failed to do so.The History Channel should stick to facts, or at least mark unpopular hypotheses as such.
