Document 5: Whale Whores: Ramsey Isler of IGN called ``Whale Whores ''an entertaining episode, but said the episode could have provided more meaningful satire and did not explain the whaling issue very well, especially considering the show's target audience was probably unfamiliar with it. Isler praised some of the individual jokes revolving around the Japanese attacks, and called Cartman's`` Poker Face'' rendition a classic South Park moment, but dismissed the Enola Gay twist as ``stupid ''. Carlos Delgado of iF Magazine said`` South Park swung and missed'' with ``Whale Whores ''.

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." While not all of the reviews were positive, they were mostly positive by the end of the first season. Much of the show's praise went to the performances of Martha Plimpton and Garret Dillahunt.
Document 8: Someone to Watch Over Me (Battlestar Galactica): Alan Sepinwall of The Star - Ledger found that the episode was an excellent showcase for both Katee Sackhoff and Grace Park, and praised director Michael Nankin who ``(infused) this episode with the qualities of a nightmare. ''Michael Saba of Paste Magazine called the episode an`` exercise in building tension through omission'' and felt the episode was ``excellent ''. IGN writer Eric Goldman praised the writers of the show for the plot turns in the episode, in particular the fact that Boomer's returning to the fleet with Ellen Tigh was in fact just a ruse. Goldman felt the subplot involving Kara was`` a bit meandering'' but that Katee Sackhoff and Roark Critchlow gave strong performances. Cinema Blend felt the writers ``threw a neat little curveball ''with the Roark Critchlow piano playing character being Thrace's father. Marc Bernardin of Entertainment Weekly felt the Boomer storyline was`` awesome'' but was less impressed by the storyline involving Thrace, feeling ``that it did n't tell us anything new ''and that the writers had written a very obvious ending to the subplot.
Document 9: 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 12: Once More, with Feeling (Buffy the Vampire Slayer): All of the regular cast performed their own vocals, although two actors were given minimal singing at their request. ``Once More, with Feeling ''is the most technically complex episode in the series, as extra voice and dance training for the cast was interspersed with the production of four other Buffy episodes. It was Joss Whedon's first attempt at writing music, and different styles -- from 1950s sitcom theme music to rock opera -- express the characters' secrets in specific ways.
