This may very well be the worst movie I've ever seen

I'm not into most kiddie stuffs anymore. But I admit that I like that movie. It's about growing-up. It's not just a kiddie movie where in every character does their overly stupid slapstick antics or every scene is referenced with facual errors. It's a good flick, nonetheless.

And by the way, how old are you when you walked out of a theatre while watching it? The movie's focus on audiences are kids, and while it's a kiddie movie, we grown-ups should not take it as seriously as if we're watching a Quentin Tarantino film or a Steven Spielberg masterpiece (unless a kiddie movie has vulgar elements that parents wouldn't show them to children). I suggest you should watch it again and and this time on a light perspective.
