Shane Black is one of the best writers ever. Every screenplay he touches becomes pure gold.
Since I've seen all the movies written by him, I've decided to make a complete ranking of his movies as writer.
Not all these movies are directed by himself. I've decided to eveluate them for the overall quality of the movie not only of the quality of the screenplay (but usually the two things coincide).
All these films are great, even the lower ones, so if you watch any of these you won't regret.
