I feel the TOS films had a larger diversity of aliens than the TNG films. In five of the six films, there were crowd scenes with a large number of aliens. TNG films didn't have crowd scenes with aliens; the films were more narrower in their scope, with the attention focused on the ship.
I read the last review, and I think the writer brought up a genuine criticism. I have found that many of JJ Abrams productions have had underdeveloped characters. I watched the series Alcatraz, and I could never understand why the director went out of his way to alienate and isolate his team. The relationship didn't undergo a change - it was the same in the end as it was in the beginning. (When I watched the Vengeance
taking out the prison, I was thinking that possible that Abrams was making a statement on this failed show.)
