I watched All The President's Men... yeah, the 1976 movie.
Watching House of Cards left me interested in political plotting in the USA so I knew this movie was famous and I watched it. It's good of course, but the ending left me completely puzzled. The movie spends 2 hours in the investigation of the Watergate break-in, and then it ends with them "aiming too high" and naming too soon one of Nixon's inside circle, and therefore jeopardizing the investigation. The movie ends there, they get scolded, Nixon on TV gets sworn in a second time, and then there's a 2 minutes montage of headlines that show that Nixon actually resigned later.
I mean, what??? the investigation should have paid off, not seemingly end bad... make this a work of fiction with no ties to reality, remove the final bit about the headlines of Nixon resigning, and you have a movie of two journalists investigating a scandal and failing in proving it. I expected some more satisfaction from a movie so famous...
