This movie is actually extremely intense so if you're reading this before watching, and are looking for a light watch, this ain't it. Other reasons to watch: the acting is great and even includes the real-life people involved (which comes off a lil cheesy at first but later turns out to be the best part of it all - would recommend for crime documentary fans). Don't wanna give too much away but definitely agree with the other reviewers on here that this movie really gongs you in the core, and unites you with the people in the story through intense emotions like excitement/adventure that turns into fear/regret.
Overall: good movie, great acting, storytelling/directing keeps you interested the whole time, gets almost too heavy but that's completely inevitable with this story.
