Speaking of Bron, is it too much to ask for Kiefer Sutherland to come back?
But, actually, I'm pretty excited. I can see this movie having a lot of parallels with the first, with the mention of heart and also one of Littlefoot's parents. If they do add Chomper and Ruby in, it will be extremely ironic for the very thing that killed his mother and took her away from him to help him find his father and bring him back. If they do take that route, I'm really excited to see how it will be played out.
The relation between Littlefoot and Bron is also a very interesting aspect to explore and look at, and could give us some very touching and heartwarming scenes. Also, when Felix stated that "it's an emergency", that makes it sound a bit more adult, and could give us some real meaning as to why Littlefoot goes off. Other than the obvious "oh he's my dad of course I'm gonna go find him", there's also the important factor of his mother was killed by a Sharptooth and then died right before his eyes, and it was, unfortunately, all avoidable. If Littlefoot thinks he can do something to prevent an "emergency" from happening and history repeating itself, leaving Littlefoot an orphan for real, then that's what he's going to do.
The Bron storyline could also give us some brotherly development between Littlefoot and Shorty, especially since he's both of their paternal and fatherly figure. It'll be interesting to see how this affects Shorty, who would, most presumably want to go after Bron as well. Think about it, Bron's been taking care of him for a very long time, unlike Littlefoot who's only known him for a short time. So, I would predict that Shorty joins the gang as well.
Hopefully this'll be a good movie. It seems like they're putting a lot of effort into this. Hopefully it pays off. I just really hope that they're going to build off the TV canon and add Chomper and Ruby up into this gig. (lol jk i just want jack bauer dinosaur back)
