re: Anyone see the Discovery channel's "Alien Planet"
Yes - check the earlier posts on it in this Web site.
The aliens were based on the creations of Wayne Barlowe from his 1991 book Expedition.
Despite the flaws, it is good to see some of the networks attempting to seriously explore what life may be like on other worlds. At least it will get the public to become more aware of the wider universe and think beyond how aliens are usually portrayed by Hollywood, which is not nearly as imaginative as it seems.
