Jeffrey Lyons was one of the big tv-based film critics in NYC (Channel 11, WPIX), when I grew up in the 1970s. Over the years, though, I noticed that he's gotten more and more Lowest Common Denominator.
Here's his typical sort of tv gig, pimping bad movies:
Film critic Ray Carney has basically declared that critics that kow tow to Hollywood are always (whether giving a positive or negative review) part of the system. This includes not giving spoilers, etc., as if the end all and be all is to sell the art, rather than make good art.
Lyons seems to be a classic (if not the worst) example of Carney's Dictum.
