The Character you hated the most.

I kinda hated the American kids the most. I dunno why. All they did was scrunch their faces up and cry and whine.

I dunno, maybe I just felt this resentment with them because of poor Amelia not even getting to go to her son's wedding without having to drag the little brats along. Maybe it's not fair on the kids to be mad at them, but I couldn't help it.

I didn't find any of the characters to be worthy of hate. All of them were doing what they thought was right, in difficult circumstances. Some made foolish decisions, but none were malicious.
Still, the Moroccan police were extremely brutal in their methods, and the US Border Patrol agents were rigid and callous. The Japanese police were presented in a much better light.

The "stupid FATASS tourist" had a lot of valid points. He was just a self-appointed group representative trying to look out for the safety of the other tourists. They didn't abandon the couple immediately, but spent quite some time there waiting for the ambulance. They had elderly people on the bus who had health issues made worse by the heat, some requiring medication that they inexplicably did not have with them. There was a valid reasoning that tourists have been killed in many cases in foreign lands without provocation. Of course, my personal opinion is those people should not have put themselves in that position if they were truly afraid of being slaughtered by terrorists or had life-threatening medical conditions they did not apparently consider fully when they decided to go on this trip. Nonetheless, I don't know if I could have left the couple abandoned in this village myself.

At first I disliked Brad Pitt's character for telling Amelia to cancel the wedding, but then I understood as the movie went on.

I thought the guys acted like *beep* when they found out the girls were deaf. It's one thing to lose interest but their smug looks pissed me off. I felt so bad for that girl, I was waiting for her to kill herself the whole last 20 minutes of the film.

Most of the characters were idiots who made stupid decisions, so its pretty hard to like any of them.

Poorly Lived and Poorly Died, Poorly Buried and No One Cried

I hated the nanny. She was selfish and just plain dumb. After all those years of raising the kids she still decides to head down to Mexico AFTER, their mom is shot and recovering in a Moroccan hospital, she is illegally in the country, she never met a single family member that could care for the kids in case of emergency, AND allowed her drunk armed nephew to drive them across the border both ways. Everyone else was just uninteresting.

Chieko exsposing herself an acting Cra-Cra as hell.
