Science fiction serials and films get a bad rap for a lot of reasons, and a lot of the more sophisticated offerings are often rated PG-13 or R, or relegated to international territories (as with Dr. Who) that come with their own set of stigmas or viewing challenges. So how are much younger kids — the sci-fi fans of the future — supposed to find suitable inroads into the genre?

Enter the SyFy Channel, which has made a mission out of peddling futuristic action dramas and apocalyptic doomsday fare to audiences of a younger demographic. The two meet in Collision Earth, a movie no one would necessarily mistake for high art, but one that nonetheless checks a lot of boxes of intrigue for less discerning viewers.

Penned by Ryan Landels and directed by Paul Ziller, the movie centers on a massive comet that strikes the sun and knocks Mercury out of its orbit, which has disastrous consequences for Earth. With the now-magnetized heavenly body drifting closer and unleashing all sorts of gravitational chaos, a disgraced scientist (Kirk Acevedo) and the lone surviving crew member on a crippled, distant space shuttle (Diane Farr) must work together to reactivate a top secret planetary defense system and try to avert this extinction-level event.

Collision Earth‘s budgetary limitations definitely constrain the scope of its story, as well as its psychological hold. And the movie doesn’t fully escape the tendency that far too many sci-fi films have to bend and bow to action rather than work through their theories on a more intellectualized plane. But if one forgives it these shortcomings and some hammy dialogue, there’s an interesting story here, buoyed by invested lead performances and competent editing. And the scariness never becomes overwhelming, making this a nice little sci-fi introduction for the younger ones in your brood.

Housed in a regular Blu-ray case, Collision Earth comes to the format presented in a 1080p 1.78:1 widescreen transfer, with a Dolby TrueHD 5.1 audio track and optional English SDH and Spanish subtitles. As for bonus features… well, apart from a couple trailers on start-up, there are none. Nevertheless, to purchase the Blu-ray via Amazon, click here. C+ (Movie) C- (Disc)
