Here are some frames from my movies where I used a Smoque filter:
It's similar to a Double Fog or a heavy UltraCon -- doesn't cut sharpness too much, creates a haze around light sources, the main problem is if you pan off of the light sources or someone crosses the frame and blocks them, the smoke effect disappears. So it's not a cure-all, but it's a useful filter for when you can't smoke a shot in a scene, or want an insert to look more like the fogged wide shot.
