The latest installment of Watch This is down to #70 The French Connection filmed in 1971.
The film editing was crude by today's standards, the plot was rough and tended to jump around and the whole thing ended abruptly. By today's standards, high school kids with a cell phone could produce a better movie, and most of the people reviewing the movie seemed to dislike it.
BUT, taken in the context of 1971, The French Connection set the standard for cop movies and almost every cop film since follows the same formula. The rogue cop who got a fellow officer killed whom no one wants to work with. They stumble upon a case. It gets endorsed by the top brass, there's a car chase, a shoot out, it all ends badly and the criminals make out better than the cops did.
I liked it, and I want Popeye Doyle's hat.
