biggest plot hole
I know this movie leaves a lot of questions unanswered and it is either due to poor story development or a loose plot. My main issue with this film was the progress of the investigation that led up to tracking Thelma and Louise. They must be the world's smartest cops because what they find out in a couple of days could take weeks or even months in the real world.
IMHO the trail they left was pretty cold. It was only by one plot contrivance after another did the police catch them. I understand how shooting Harlan was supposed to be connected with a similar crime from Louise's past but how it was uncovered just seemed forced (somehow they managed to get witnesses who saw the green Thunderbird (at night???) even though one of dozens of cars could have been the getaway car). And then J.D. was arrested, that is how they found out about the money, but why was he arrested?
I know this is supposed to be a feminist hit-and-run/road trip movie, but I had a hard time believing in these efficient, omniscient police, it made the whole thing look ridiculous.
