Mannix put 99% of the trash that was on TV THEN to shame. I guess that means there's more quality now then there was then.
(Go take a look at the crap that was on then and compare it to Dexter, Mad Men, Game of Thrones, etc. and you'll realize that TV is FAR better now than it ever has been. TV in the 60s was mostly a white supremacist fantasy, and in the 50s it was constant killing in westerns.)
