I wouldn't call "We're Back! A Dinosaur's Story" simply a kiddie version of "Jurassic Park". I found it more interesting than that. Like the former, it calls into question the security of bringing beings from one era into ours. But it really opens my eyes when I see who provided the voices: John Goodman, Rhea Perlman, Jay Leno, Walter Cronkite, Julia Child, Kenneth Mars, Yeardley Smith, Martin Short and Larry King. To paraphrase that: a given actor, the "Cheers" woman, the "Tonight Show" host, the Most Trusted Name In News, a famous chef, the "Young Frankenstein" police chief, Lisa Simpson, one of the Three Amigos and the CNN guy.
But I guess that I shouldn't focus only on the cast. I thought that this movie had something for both children (purely fun) and adults (natural history). True, it's escapism, but the perceptive kind. I would actually say that John Goodman doing Rex's voice here is sort of a precursor to his voice work in "Monsters Inc". Worth seeing.
