I actually liked movie #6 and #7 more than the original. I mean, the original was great, and it was more mature and heartfelt than the sequels, but I thought that the original LBT movie didn't really devote much time to developing characters - it was all about reaching the Great Valley. In any case, as for WHY I liked #6...Doc. Doc freaken. Rocks. He's is a lot like me - I don't like to socialize, but when people talk to me I'll respond, everyone knows nothing about me, I'm naturally calm but can have a flare of attitude, and so on and so forth. That's the main reason. Another is...well...the Allosaurus - or the gold and brown sharptooth at the very least if its species isn't specified - rivaled the ferocity of the T. Rex in the original, and dang, that thing just didn't. Give. Up! Which was why I liked it, even though it was supposedly killed by a longneck-induced rock avalanche...
Movie #7...there's a lot of reasons why I liked it. Though the animation was horrible, it gave Petrie some limelight, which I thought we seriously needed after all of this attention focused on Littlefoot. There were interesting, complex characters like Pterano and deceitful characters like Rinkus, and while the story was simple it branched off into a couple semi-miniplots (Ducky being kidnapped, Petrie trying to prove that his uncle is good, Rinkus and Sierra planning rebellion behind Pterano's back, etc.).
