Henchmen are good and get improved with the Hotu expansion.
Our escape from undermountain is "based" on the PnP boxed version but it would be almost impossible to totall recreate that box in a computer game.
For the chase cams I usually just play around with mine and adjust manually. I have a wheel mouse with a third button. When I press and hold down the button I can adjust the camera, zoom, change angles. makes it really easy to play.
