Michael Crichton's Coma was one of the earlier films released on DVD, coming out in 1999, at a time when the format had already (and unexpectedly early) become profitable, but the technology was still new. Warner Home Video tried to be ambitious and generous, but this disc is hampered by the limitations that existed in the format. Each side has a different transfer of the movie, one letterboxed to the non-anamorphic 1.85:1 aspect ratio of the original release, and the other full-screen (1.33:1). The letterboxed version is preferable, maintaining Crichton's original tight image framing, which enhances the feeling of claustrophobia and paranoia one should get while watching the movie. The 113-minute film has also been given a whopping 30 chapters, which break the plot down very neatly. The flaws can be found in the details; the Dolby Digital Mono audio, though clean, has been mastered at an extremely low volume level, which is likely to require viewers to have to drastically turn up the normal setting on their televisions just to get to an acceptable volume -- and that's essential to appreciate the complex and subtle score by Jerry Goldsmith. Additionally, this was an early digital transfer, and while it does run circles around the old laserdisc edition, there are momentary digital artifacts that probably would be avoided on a modern transfer. The only bonus feature is the original trailer, which must be accessed manually along with the main menu -- otherwise, as with many discs of this period, the movie begins automatically on startup of the disc. There are also options for French and English subtitles.
