I think the plot for LBT 12 and 13 could have been used as TV show episodes instead of actual movies. They didn't seem too developed enough for a whole movie.
Personally, I enjoyed LBT 7, but I do not believe it is the best. I would say LBT 5 was the best sequel (I probably changed my mind from before). It gave the dinosaurs the first conflict which really forces them to leave the Great Valley (the water crisis in LBT 3 was bad but not enough to force them to leave). In my opinion, it reflected how in real life people left their homes and went to America for a better life, but the journey was perilous. It also shows that in a time of crisis, a scapegoat must be found and dissension erupts in a once calm group (Topsy causing most of the argument and going as far as blaming Littlefoot for Cera leaving).
What really clicked for me was how the movie revived past prejudice themes between the characters and Chomper. Cera is the main character to continuously show such feelings towards Chomper, constantly holding her grudge onto him when he bit her in LBT 2, and eventually for a brief moment Petrie and Ducky begin to agree with her that Chomper is too dangerous. I thought this brought up a great conflict on trust and moral beliefs, as Littlefoot never doubted that Chomper would not hurt them despite how the others felt.
The song Always There is in my opinion the best song of the sequels. It shows the true message that nobody is truly alone and there's always someone there for you whenever you need them. Also beside the message, this was in my opinion the best desplay of singing for Littlefoot, even though it was Thomas Dekker instead of the original voice actor.
I realize this is ranting and off topic, but I had to get my opinion out :blink:
