That end was so ridiculous haha
This was incredibly hard to watch at times but I guess that's just how perception changes over time.
The plot is generally decent, nothing to write home about but it has its few good twists.
Because of the dated acting, however, I found it impossible to read the characters which of course isn't inherently bad but lessered my enjoyment of the movie as the pursuit of the truth is one of the - if not THE - defining elements of any crime/mystery thriller both for the protagonist and the viewer. So when the acting is unreadable and you're wondering if any of the characters are in a stable mental condition, this element is taken away.
A classic movie although a bit slow. Some pretty good twists. Easily worth a watch.
