Il caso Yara: oltre ogni ragionevole dubbio

This documentary cought my attention, it is heartbreaking as any similar case would be and I was really interested in finding out what happened but on the half of second episode I had to stop watching because of disturbed timeline. Constant back and forth between various years is making me nervous and I can't follow any more what is happening when. Don't understand the reason behind this but I see it often in documentaries lately especially true crimes. It's purpose is I suppose to make dynamics which is fine but should be made moderately. This just confuses, iritates and makes documentary impossible to follow.
