Sometimes I like movies because my 3-year-old likes them, so I'm going to try to remember what it's like to think of a movie objectively, or based upon whether or not I liked it.
My biggest complaint about "The Good Dinosaur" is that oh my gosh it's slow. The second is like unto it, two, maybe three, interesting characters and that's it. Arlo the dinosaur is great. Spot the human is the greatest thing ever. The triceratops or "the collector" is so creepy that I can't tell if I love him or if he gives me anxiety. I quote him the most though, so that says something.
I love that Arlo has panic attacks. Finally a cartoon character understands! I love the metaphor about the storm and fear, and the message about being brave. But there are sad parts. I don't know if it's the gut-wrenching sob fest that is "Inside Out," but it has me sobbing. (Then again... I'm six months pregnant, and just about anything makes me cry even without the help from whack hormones.)
It's not a bad movie. It's just a slow movie, and my toddler absolutely adores it, so who am I to judge?
I'd watch it for Spot alone.
Oh, one more thing, it's like several different movies. "Annie." "Twilight." "The Lion King." "Homeward Bound." What else? I'm sure you've got some.
