it isn't that bad at all actually... the acting and story yes aren't the greatest and are cliche and just rather plastic
but the production design and overall look beats the hell out of nearly every other movie that syfy has made or been involved in in terms of production.
Some sequences were solid, what most impressed me so far are the visual effects for a TV show, not bad at all actually.
It's not great by any means but after seeing the first part it should get like a 2 1/2 star out of 4.. it's decent enough
