For those of you who have worked in fine dining kitchens, is the T.V. show Hell's Kitchen anywhere close to the reality of it?

Is my meal, my table’s meal the result of everything being timed to the minute, possibly the second and close communication between the prep chefs, sous chefs, the head chef, everyone on each station, everyone involved? Maybe there isn’t so much yelling and hostility but it seems really stressful. I have noticed a lot of chefs on Hell’s Kitchen smoke. If it’s that stressful I can understand why.
