Hmm... well just the music in itself throughout the movies amplified some of the 'scary ' scenes making them even more emotional and empowering.
But anyway, on Land Before Time II, I was scared and anticipating when I saw them jump across the ledges to get away, and then when the gang landed in the mysterious beyond, that was utter creepy (well I was 5 xD).
Hmm... moving on, the first time I saw the velociraptors on LBT III (or utah raptors?) was a little 'creepy' them trying to all escape in the bone infested land, but not too much.
I do agree, the song on the fourth one was a little scary at first (mostly because of all the words). The mists were a little frightening when I first heard of them from that old longneck and then thinking about the music that plays in the mysterious beyond.
The fifth movie had the running scene-- that was a really strong image the way the colors changed and all. I wouldn't say I was more as scared than hoping they escape and live (even though they would but still!). You could also say the desolation of the desert (never before seen in LBT series besides the first), the mysterious missing carnivore's footprint, and the locusts.
Nothing on the sixth one scared me, though yeah the bee stings were abnormal.
The seventh one had THE MOST SCARY SCENE of all the Land Before Time movies! Seriously! Remember when they were describing what pterano had did? I was so scared man. First the dinosaurs already go into a somewhat creepy place that seems like paradise, but then it escalades into the most gruesome and horrifying things you'll ever see with dinosaurs. They have nowhere to go, and all die, including one SCRAPING HER CLAWS on the rock to not fall and then falling down a huge hole (with of course waterfalls to make it even more creepy because it's so deep). Yeah... :unsure:
Starting from the eighth one, I was not only older, but they were a little more lighthearted
. Maybe when Ducky was first going into the cold beyond, it gave you creepy thoughts, but from then on, the rest of the movies (and the eighth) were not scary and creepy as the the first ones
(I was also older. I watched the 10th one when I was 12! [i'm 17 now])
