Was there anyone particularly intelligent? Gurathin and Mensah were probably the closest. MB maybe.
If there was, none of those people were using that intelligence in service to good judgment.
I feel like the corporation people didn’t seem stupid. Not evidence of intelligence, and there wasn’t enough time with them to tell, but “we won’t insure you unless you have security” seems pretty reasonable.
In the books, yes, most of the characters, both the “good guys” and the “bad guys” are moderately to very intelligent.
