The Brace Little Toaster is a great film, but you might want to preview it yourself before watching it with your kid. There are some scenes of peril and (machine) death that are surprisingly intense for a kids' film and your kid might not handle them well.
Oh man, you're bringing the flashbacks. My siblings watched that movie constantly when I was a kid, and some of those scenes traumatized me for years (I was a sensitive kid).
