I've gone way past the one-third point of this movie and suddenly it's starting to seem familiar. Is this what I think it is?
Change the names.
Change the country and cities.
Change the ethnicity of the perp.
Make the two girls lesbian lovers in a relationship.
If this isn't clearly Hollywood agenda to you bastardizing a true story, then go take a cold shower and re-examine your brain.
I have some sympathy on Matt Damon for choosing this role and the script, because his character is interesting and the script is complicated, but, dude, this was a bad pick. After looking at the script, he should have been like Homer and disappeared back into the bushes. Don't touch something like this with a ten foot pole.
