So Disappointing I'm writing a review

Rating: 4/10 (31 March 2016)

This movie doesn't make sense. The trailers made me think I thought I'd see Emily Blunt kick ass. Instead all I saw was Emily Blunt flail around and seem incompetent, have ethical dilemmas that I didn't understand, and make me forget she was even an FBI agent.
Copied below from Karl Self's review because I can't figure out how to link it. I'm copying it because I had the exact same questions.
*** Spoilers thick on the ground from here on *** Things that made no sense:
What's the point of the horror house at the beginning? If the cartel is using it to dispose bodies, why would they shrink-wrap the corpses? Why are there gun-toting criminals in a house full of incriminating evidence? Why are the corpses behind dry walls (is the cartel planning on renting out the house)? Why is the trap-door booby- trapped? Why do police have to anticipate that in about six months every further crime scene will be booby-trapped if they don't stop the cartel now? When they are illegally extracting the cartel boss from the Mexican prison, why are they doing it in a highly visible convoy? If they anticipate being ambushed just before the frontier, why don't they keep a lane open? Why didn't they use a helicopter? Why don't they just torture the guy in Mexico? What are the ambushers trying to achieve? What is the role of the crooked cop? Could he be any hammier than carrying a gel bend around that the cartel uses to hold their bankrolls together? And on and on.
