Rear Window

The best set design I've ever seen paired with one of the tightest scripts I've ever seen makes for an incredibly entertaining sleuth that, despite being shot almost exclusively from one angle, never gets boring. The absolute best kind of mystery writing; it's interesting the entire time and doesn't pull out some bullshit completely unpredictable plot twist at the end that the viewer never could've guessed. Most characters are viewed from a long distance, and yet the viewer learns so much about them as the plot progresses, without a line of dialogue being exchanged between them and the leads. Everyone has a story, and somehow through the countless layers of the plot, everyone gets a satisfying ending. Find yourself some homies who will sleuth with you without batting an eye.
