Walking with Dinosaurs/Heartwarming


 * Beasts has at least two. By the end of "Next of Kin" when the australopithecines team up to drive off the big cat Dinofelis from a threatened youngster, and when the matriarch of the mammoth herd welcomes the delayed female and her calf in "Mammoth Journey".
 * Making the ending of "Next of Kin" was that Blue was the Butt Monkey of the Australopithecus tribe, an orphan who was basically a hanger-on to the tribe after his mother died. The fact the tribe considered him worth saving make it extra heartwarming.
 * The ending to Walking With Dinosaurs would be a Tear Jerker, except for the very end, which shows (just like ending to Jurassic Park), that even though the dinosaurs are gone their descendants -- birds -- are still with us.
