For those who are familiar with NGSS,what are your thoughts?

It appears not to have garnered the negative backlash of the Common Core standards but the difference may partly be that only states who want higher science standards are adopting them and Science is not perceived as fundamental in the same sense as Math and Language Arts.

Our district is in the process of implementing NGSS and the standards will be fully implemented across all grades within the next couple of years.
