Wasted 3 hours of my life for nothing – iMovie Review

I’ve been working on this movie for 3 hours now (its 6 minutes long.) and 3 times, the audio shifted toward and I had to take 10 minutes to fix them. When I was about 4/6 minutes in, I tried moving an audio clip and iMovie just died. Black screen. I couldn’t play the movie. I could only move it and see all my hard work go into the toilet. iMovie is iRuinyourlife. Also, I made a 8 minute movie not too long ago, and the bug didn’t occur? Is this some kind of joke?
