I do not see anything wrong with something being 'entertaining'.
In fact in my own personal belief I think some of these ET races are envious of us Humans because we have such a range of emotions.
Life is meant to be ENJOYED and I think some of these ET races have forgotten that.
I seriously think they are confused by it and wonder what it is all about.
In other words: "The can't get the joke..."
I also believe we are more advanced then many ET races because of our emotions.
If only we can learn to control ours a bit better.

We just are not as advanced in scientific areas so we can think we are not advanced at all.
