Most of the time it's subtle, but on several films it is really beneficial.
- JP3: The scene near the beginning where Dr. Grant and his charges are flying toward the island. The scnen begins with the airplane flying onscreen from 'below' the camera, with complemetary rear to front vroom sound that is very convincing.
- JP3: Airplane crash. As the airplane disintegrates you can clearly hear the cockpit warning beepers quietly doing off front center, while parts of the plane are loudly knocked off left and right and the parts fall away to various places in the rear. Very cool.
- Lara Croft - Tomb Raider: Opening scene where at various points Lara is shooting toward the robot, which is between you and she. The shots are clearly audible from the front center, with some whizzing past and hitting the wall behind you. You will duck the first time this happens.
Lots of others. The entire attack in Pearl Harbor. Airplane sounds in Space Cowboys. Even scenes with ambient sound fields (rain, wind) are more enveloping.
If it's not prohibitive I'd go for it.
