Cult classic for a good reason
This movie has attracted a enthusiastic following over the years. It has a great story, deeply developed characters, and clever plotting. The 4K disc picture quality is excellent, as is the sound. It's a movie I watch regularly over the years, which is the test that counts—repeat viewings (there is always some new detail to discover, and others to appreciate).

An Archival quality 4k
The Director's Cut is marvelous and this new 4K release is sensational. The image quality is remarkable and yes, noticeably superior to the Blu-Ray release. The audio is also worth mentioning here, so do not think you will be in any way disappointed.
While the price is a bit step, I just waited for a good sale and nabbed it at 50% off.

One of my favorite movies
This Director's Cut takes an already excellent movie and makes it even better. I seriously doubt I'll ever watch the theatrical version again.
