With the advent of cheap CGI I'm starting to wonder if maybe it's gotten a little too cheap. The Captives is only passable entertainment (although not a complete waste of time for those inclined) as the lack of budget really does seem to impair the underlying vision for the whole film.
Pretty much your basic bug hunt science fiction film, aliens have invaded Earth with the survivors living under (formerly) secure domes but the creatures are now evolving and are able to penetrate Earth defenses. Xu Dongdong leads the military team trying to overcome the challenges the invaders are throwing their way as well as some personal demons of her own but the price grows increasingly high.
I can't point to any one thing that really stands out - the sets are cheap, the CGI goes between barely OK to passable video game level but the story did keep me from switching off. If you've got some time to kill and need a dose of alien invader fu this might be worth checking out. More like a 5 1/2 than 5 stars.
