Watched Sicario last week for the first time and was underwhelmed.

3 good scenes - when they leave Mexico after kidnapping yer man, when they enter the tunnel and when he gets into the cartel lads house at the dinner table. The rest was just yer wan figuring out that she was only there for legal shite. Feels like they were trying a bait and switch on the watcher that she was the main protagonist but GUESS WHAT the other guy was all along, which was very obvious from the start.

What am I missing here?
