Angst? What Angst?: The deaths of Patchi and Scowler's entire family in the 2013 movie. By the next morning, they're done mourning their father, and the loss of their mother and siblings is never even mentioned.
Author's Saving Throw: The powers that be seemed to have realized what a misstep the voiceovers for the 2013 film were, because now they're going to re-release the film (at least in the UK at an unknown time) without the voiceovers. Even better, Benedict Cumberbatch is going to narrate!
Better on DVD: For those who disliked the childish dialogue in the 3D movie, at least. The Blu-ray release has the "Cretaceous Cut", which eliminates it completely.
From the general scientist/paleontologist community, but mostly from those to whom scientific accuracy is Serious Business and any amount of speculation is intolerable. One such person infamously labeled the show's paleontology consultants "prostitutes" for "selling out" their knowledge to a fancy TV show.
Pretty much everycritic and their mothers are attacking the 3D movie. Few people are willing to contest them.
Of the 3D movie, Gorgon. He's treated as the main villain, and yet just a predator trying to survive and feed his pack. Probably justified, though, as the story is told from the point of view of his prey.
While they didn't become stock, Ornithocheirus and Tapejara became fan favorites after this show and were given more attention in educational dinosaur books. The Ornithocheirus character became particularly popular due to the tragic outcome of his story.
Gorgon from the 3D film, partially for being one of the few named characters not to receive an annoying voiceover.
Although for characters that do have a voiceover Alex has some popularity with the viewers, considering him to be less annoying than the others and he even does a Moment of Awesome.
The "Cruel Sea" opening reminds people of the ending to Jurassic World.
In "Giant of the Skies", the tapejarids are depicted as having black bodies and red crests. In 2017, a tapejarid was discovered with preserved melanosomes (pigment cells). Guess what colors its body and crest were.
Moral Event Horizon: Scowler almost crosses this when he disowns Patchi and leaves him stuck in a ditch to be killed by predators for leading the herd away from a lake of thin ice that he himself led into (and never shows remorse or responsibility for it). By almost as in he redeems himself as he's getting mauled by Gorgon and Patchi rescues him.
The final fate of the tyrannosaurid family at the end of "Death of a Dynasty" rather comically clashes with the grimness of the scene. To elaborate: The mother died from her leg wound, with the surviving infants clustering around her body. Then the meteor shockwave hits. The babies get suck up by the wind and zoom away, followed by the mother's corpse being lazily dragged after them.
The Liopleurodon snatching up the Eustreptospondlyus is easily the most memorable moment of the original series, and immediately put the former species on the map.
The Diplodocus hunt is the main set-piece of The Ballad of Big Al.
Patchi nearly allowing himself to be eaten in the 2013 film was seen as the most jarring and nightmarish in an otherwise unremarkable film.
Nigel nearly getting eaten by the Megalodon for Chased by Sea Monsters. The grueling fight between the pack of Giganotosaurus and Argentinosaurus for his other two specials from Chased by Dinosaurs.
Special Effect Failure: Even these shows weren't immune to this: the most common goofs are CG clipping errors (like when the mammoth's trunk "merges" with its tusk), wires from the animatronic models or parts of the people controlling them being visible, and shadow/reflection effects being messed up. Some are obvious, others you only catch if you watch the clips frame-by-frame.
The film has no lip synching, leading to speculation that it was supposed to be a serious documentary and was changed to a comedic film a la Ice Age at last minute. Cue outcry of They Changed It, Now It Sucks.
The animals in the earlier series often suffered from weird clipping and deformation. Sometimes during motion, their skin-textures would overlap and clip through each other near the joints, creating odd-looking "seams". There were also some rigging problems evident, like the shoulder-spikes of Polacanthus moving separately from its skin, or the upper teeth of the Diplodocus stretching when they open their mouth in a couple of shots. These issues were gradually ironed out as the series progressed.
So Bad, It's Good: Arguably the 2013 movie, with its inept childish dialogue, over-the-top cliché plot and gratuitous sexism. Others just see it as horrible, though.
Juniper, from the 2013 movie, is considered a bizarre Gender Scrappy for being a Flat Character and evident of the gratuitous sexism the movie shows.
Alex the Alexornis from the same movie is a bizzare example of a Reverse Scrappy, being one of the only characters who isn't nigh-universally considered annoying and stupid. Being voiced by John Leguizamo certainly helped.
Squick: Early on in the 2013 movie, a hatchling Patchi is defecated on by a larger dinosaur. This wouldn't be so bad if he hadn't received a gaping open wound in his frill less than a minute before.
They Changed It, Now It Sucks: Many a dinosaur fan and Walking with Dinosaurs fan have complained about the 2013 movie humanizing the animals too much.
The cynodonts from "New Blood", and their babies for that matter. They're like little, half-bald puppies.
The baby Diplodocus from "Time of the Titans". At certain points, they even sound like human babies! And rather than being creepy, the effect is downright adorable.
The Cryptoclidus and baby Opthalmosaurus in "Cruel Sea". The former is basically a Jurassic seal (although closer to a fully marine penguin in Real Life… still sounds cute) and the latter is essentially a Jurassic dolphin.
The Tapejara from "Giant of the Skies" and pretty much every pterosaur in the series. The fact that pterosaurs were this in real life certainly helps.
The Leaellynasaura from "Spirits of the Ice Forest". All of them.
Special mention must go to Sea Monsters. It features pre-historic creatures underwater and interacting with Nigel.
The arena spectacular for the sheer spectacle of seeing life-sized dinosaurs live in front of you.
Although the WWD movie got mostly negative and mixed reviews, the visuals have impressed mostly everyone, whether it's just the CGI or the 3D effects as well. The bulk of the critics single them (as well as John Leguizamo's "spirited way with words") out as the sole saving graces of the film.
What an Idiot: Nigel. Oh, Nigel. "There's no way I'd even think about jumping in waters where a mega-sized piranha is the least of your worries... OH!!! A TURTLE!!! WHERE'S MY DIVING SUIT?!"
Tyrannosaurus rex in the final episode. First, she loses her eggs after volcanic activity kills the embryos. Then, she seeks a new mate and then drives him away, but after laying twelve only three hatch. Then, one of her babies dies, implicitly at the teeth of its own siblings. Then she is fatally injured by an Ankylosauruswhile trying to protect them and suffers a slow agonizing death shortly after. The only saving grace is that her death meant she didn't have to die in the mass extinction.
The old Ornithocheirus. He risked his life flying all the way to his old mating grounds, is driven away the minute he gets there, and dies of exhaustion without managing to mate at all.
