James Poniewozik of "Time Magazine" was upbeat, stating that "Neff is amiably charming, Dillahunt and Plimpton give their characters a realism that belies the pilot's often-contemptuous jokes, and maybe 20% of the first episode shows a sweet-heartedness that rises above the easy white-trash humor."

Document 14: F/X: Vincent Canby praised the look of the film in his review for "The New York Times", writing, "the movie, which looks as if it had been made on an A-picture budget, has a lot of the zest one associates with special-effects-filled B-pictures". Roger Ebert gave the film three and a half stars out of four and wrote, "This movie takes a lot of delight in being more psychologically complex than it has to be. It contains fights and shootouts and big chase scenes, but they're all firmly centered on who the characters are and what they mean to one another". In his review for "The Globe and Mail", Jay Scott wrote, ""F/X" is simply out to give a good time, which it does superbly". Paul Attanasio in his review for the "Washington Post" praised Brian Dennehy's performance: "Dennehy brings magic to the role - he's large, and he enlarges it. With his sly eyes and little can opener of a nose, his shoulders a yard wide, his hair massing in gray curls behind his ears, he dances through the movie like a mastodon in toe shoes". In his review for "The Sunday Times", George Perry praised the film's premise as a "nice idea, but the effects themselves are merely ingenious when they might have been spectacular". Sheila Benson wrote in her review for the "Los Angeles Times", "Where "F/X" floats above the crowd are in its performances; in the perfection of Miroslav Ondricek's photography, Mel Bourne's production design, John Stears' effects and Terry Rawlings' crisp, succinct editing; in the virtually unpredictable twists and turns of its plot, and in the sheer joy of watching a hero use his skill and his wits to solve a problem".
Document 15: Spectre (2015 film): Christopher Orr, writing in The Atlantic, also criticised the film, saying that Spectre "backslides on virtually every [aspect]".
