One of my closest friends gets very emotive playing D&D - cheering crits and bemoaning NPCs successes - to be honest, I find it all part of the fun.
It's a bit like being at work, where I need to assess people quickly and adjust my approach, the same applies to DM'ing. That said, sometimes I heap misery upon misery - and they keep coming back. Last night they got jumped three times and set off a nasty trap - in between the roleplay and exploration and a couple other fights - yet they're all stoked for next week's episode (mainly because they finally got to grips with the current antagonist - and chopped his head off!).
