re: Dear Zachary...the most shocking documentary I've ever seen

It's awesome.

Definitely not for the faint of heart, and it will make you literally hate a person you've never heard of in your life. I know it's brutal (and it fricking is), but the end with the parents is so incredibly uplifting and heartwarming. It's truly a great documentary, and although some parts are fricking maddening, the ultimate message behind the film is great.

It's a must watch IMO, although it's likely rougher on you if you have kids of your own.
