Whenever scenes are sped up and the people and/or the cars move super fast to the point of leaving trails on your screen, it makes me dizzy. It is a calm, relaxing and enjoyable basically 'slideshow' ( although there's moving images) of some beautiful and wonderful places on Earth I know I'll never see, so that part was extremely enjoyable. I even saw a few things I've never seen before, but really, if too-fast of movement during time lapse sequences makes you dizzy or ill THEN DON'T WATCH. I got sick to my tummy only 30 minutes into it.
