Great show, last season there were several delays with new episodes arriving on Google Play. Cautiously giving 3 stars while I wait to see if season 10 new episodes arrive on time and decide if I want to buy a season pass. Frustrating that I can't see if the price they're offering for season 10 now is in HD or not.

the show started off well, and even talked about new gizmos and emerging tech, but soon fell into boring TV relationship rut.

If you're a high-school drop out with no taste and like watching the same plot line over and over again. This is the show for you.
