Se7en
Seen this one too recommended a couple times and have been in my watchlist for 1,5 years. After that much time I made myself watch this movie.
Troughout the film, every second of it was coated in a sinister "vibe", and the plot was also amazing.
Every scene was felt crowded by people, furniture or "things". Brad Pitt nailed this character really good, and not to mention Morgan Freeman too.
The main act behind the movie was the 7 deadly sins and for heaven sakes it did a good job. Every victim represented a sin and how the last sin was carried out in a very good way. Looking back at Brad Pitt's character, it was foreshadowed from the first second that he will be the wrath.
The yellow-ish color usage paired with the concept and plot made it so much better.
There's nothing much more to say
For me the plot was the best part of the movie and conceptually was a fresh and cool representation of the seven deadly sins.
