Malfunctioning app!!! – iMovie Review

I don’t know what it is about this app. I waste 45 minutes of my time trying to make a video then upload it to Facebook. Then when I try to play the movie it will not play it just disappears with the exception of the sound. Why will it not work what is the problem why hasn’t it been resolved???? Something needs to be done to fix this because it is malfunctioning big time!!!
