Should you be emotionless during meditation?

I don't think you should be emotionless. I think that, in a way, you shouldn't be anything, you should just be there in that moment.

By that, I mean, you should just let what ever emotion that comes up be, and just watch it and understand it. Same as thoughts, you shouldn't be fighting your thoughts during meditation, you should just be watching them, not trying to alter them or control them, just letting them be until they eventually drift off.
