Our Culture is negatively orientated and "Ain't It Allfull sells, be it books or news. We are culturely imprinted from birth with anxiety and negative thinking. yes there are bad things happening to all kinds of innocent people. Be aware of this, but don't "crank" on it.

Hollywood has become more negative and nasty over the years to being literally offensive in some cases.

I found good feeling movies like Avatar and Life of Pi to be uplifting and I connect with them better than I do with the depressing ones. Be selective as you are doing.
