haterofcrap I'm not very much into animated films (In fact, I hated most animated films) or documentaries, but I love anything related with aliens, and that's why I liked this movie so much. This documentary was pretty interesting, from beginning to end. The CGI was pretty impressive, it wasn't so good as the incredible CGI used by James Cameron, but it was pretty good anyway.This was one of the best documentaries that I've seen in the recent years. I wish there were more documentaries like this (Yeah, I know that there are some series made with the same style of this movie, like "Walking with Dinosaurs" or "The Future is Wild", but "Alien Planet" was better than those series)However, it is an awesome movie, with some awesome CGI and about awesome aliens. A combination like that just cannot fail.

starrborrn this is the first time i have seen a show that actually depicts what could be out there in a scientific fashion.The way we can calculate the possibility of life is by the Drake Equation, created by Frank Drake in the early 1960s. It states: N= (r* x fp x ne x fl x fi x fc) L where:N= number of possible civilizations to communicate withR* = is the rate at which stars capable of sustaining like are formedfp = the fraction of these stars which have planetsne = the number of planets similar to Earth in the planetary systemfl = the fraction of the Earth-like planets that hold life fi = the fraction of life that becomes an intelligent civilizationfc = the fraction intelligent civilizations that attempt to communicateL= the number of years the civilization remains able to communicate.When these numbers are taken into consideration, we realize that there is a great possibility of life out there. There are about 400 billion stars in our galaxy, so there could be life right next door (relatively speaking, since that may be hundreds of thousands of light years away). Even if there is no life in the Milky Way, there are billions of other galaxies to turn to. We likely will not contact such civilizations in our lifetime, but it gives us a new kind of hope and dream for the future of our planet and the future of mankind.so Darwin 4 could actually exist out there somewhere.

s c It seemed very interesting to me upon first glance, previous "documentaries" shown on Discovery had some scientific background...but this one seem to be mostly fictional...The whole time I was watching, I was hoping "so is there actually something factual we discovered that led them to make these surreal creatures? like they found some sort of tracks, or remains, etc(kind of like the shows they did on raptors- they had more proof... or are these just figments of imagination?" I was hoping for a better conclusion than "ooo, there's more possibilities to life in other planets than we first thought"...Watching it was interesting, but the fact that it was based on wild guesses and creations of mind without any actual findings is simply a turn off ... I believe there's extraterrestrial life too, but I didn't need to waste 2 hours to see a "documentary" to convince me, I could've just gone renting a Sci-fi movie if I wanted to be intrigued... The delivery of the story was good, the graphics were fantastic, but the realism, un-realism rather, is a major negative blow to the show...

tauceti96 An intriguing and engaging exploration of an alien world. The CGI was excellent all around with some breathtaking views of the flora and fauna of Darwin IV, a world about 6 light years from earth. It really was fun to watch. The achilles heal alluded to in the summary is the overly optimistic view of our ability to build the software necessary to carry out this venture. I'm a programmer with 12 years experience and I can tell you in no uncertain terms we are not even close to being able to program an AI like Leo. Every "breakthrough" in software development productivity since the move from assembly to C in the early 1970s has been a big gimmick. We need at least one and probably two massive breakthroughs on the same order to pull it off and I gotta tell you, I haven't seen any sign of it even on the distant horizon. Maybe someday this trip will be feasible, but not until software construction is as second nature as bridge building.Still, all in all, definitely worth watching.
