The CGI work is nice, and the interviews with the scientists are nice, but I guess I'm too much of a space geek to find a lot of credible. (Surprise!)<br /><br />The first problem I have is with the probes themselves. They enter the planet's atmosphere using craft which look like variations of the space shuttle. Uh, yeah. You send a probe 6 lightyears from Earth and you use something as bulky as the space shuttle to deliver it to the surface. I don't think so. Then, when the actual probes are deployed (there's 3 shuttles, 2 survive, each one contains 1 probe), most of the shuttle is simply discarded. Seems to me that it'd make more sense to have those do something if you were actually going to use them. That way if the mobile probes end up getting clobbered by something on the planet, you've still got something there, returning data. I mean, it did take 42 years (according to the program) for the probes to get there, so you'd want to maximize your return. IMHO, a whole bunch of tiny little probes are going to be better than a couple of big probes. There's an orbiting mothership/relay station around the planet, which is what brought the probes there, and when one of the probes goes AWOL, the narrator seems to indicate that it's impossible for the mothership to find it, because of how small the probe is. Again, I don't think so. Given that the program takes place X number of years in the future (plus another 42 years for the probes to get where they're going), image resolution capabilities are going to be advanced enough for the mothership to spot the probe easy. I mean, for Og's sake we've apparently managed to find the Mars Polar Lander that got lost, and we haven't even managed to send anything to another solar system yet. Are we supposed to believe that we've figured out how to create sophisticated AI systems, travel at 20% of the speed of light, and other such wonders, but have lost the ability to make a decent camera?<br /><br />The next problem I have is with some
