Shades of Gray (Star Trek: The Next Generation)

During a geological survey on Surata IV, Commander William Riker is struck by a thorn growing on a motile vine plant. The away team immediately beams back to the Enterprise, where Dr. Katherine Pulaski finds out that the thorn has released a deadly virus into Riker's body. Within a matter of hours, the virus will reach Riker's brain, killing him. To try to save Riker's life, Pulaski puts him into a machine that will artificially stimulate his brain neurons, keeping them active and resisting the virus. This causes Riker to dream of his past adventures aboard the Enterprise. Riker's first dreams are of reasonably neutral occasions, such as his first meeting with Lieutenant Commander Data. He soon moves on to more passionate and even erotic dreams, such as meeting the cheerful young Edo women on Rubicon III, the matriarch Beata on Angel One, and the computer-generated holodeck woman Minuet (Carolyn McCormick from "11001001"). However, while pleasing to Riker's mind, the passionate dreams only worsen Riker's condition, as the virus feeds on the positive endorphins his brain is creating. Pulaski and Counselor Deanna Troi therefore agree to try to make the machine evoke negative dreams instead. Thus Riker dreams of Lieutenant Tasha Yar's death, and the apparent death of Deanna Troi's child. This has the desired effect, as the negative endorphins drive the virus away, but the endorphins are not strong enough. As a last resort, Pulaski uses the machine to evoke dreams of raw, primitive feelings of fear and survival. Thus Riker dreams of fighting the tar creature Armus, the alien-controlled Admiral Gregory Quinn, and the Klingon officer Klag on board the warship Pagh. Seeing that the raw emotions work best, Pulaski intensifies the dreams to come at a more rapid pace. This finally kills the virus and Riker recovers. ==Production==

The episode was intended to save money at the end of the season by being a bottle episode which featured few additional characters. The reason was that the show had overspent on the episodes "Elementary, Dear Data" and "Q Who", and Paramount Pictures was holding the series to their overall season budget. It was the last episode on which Maurice Hurley acted as head writer; he referred to the episode as a "piece of shit" and "terrible, just terrible". He turned in the idea of a cheap clip show to save money and wrote the first draft of the script, with Richard Manning and Hans Beimler conducting re-writes. Ron Jones created the music for the episode, including a three note motif to represent the virus that infects Riker. Themes build as the episode progresses, with elements from "Infection Spreads" which is played over the scene between Riker and Troi move into the pieces "Shades of Pleasure" and "Earth Boys Are Easy" which is played over the pleasurable memories. String instruments and flutes are added to "Shades of Sadness" which played over the unhappy memories, before it built to a climax in the intense memories in the pieces "Critical Condition", "Shades of Conflict" and "Final Intensities". Several scenes retained the compositions from the episodes, including pieces by Dennis McCarthy, while others by McCarthy were re-composed by Jones. ==Broadcast and reception==

"Shades of Gray" was first shown on July 17, 1989 in broadcast syndication. It was the final episode of the second season and was watched by 9.8 million viewers on the first broadcast. It was the highest number of viewers for an episode since "Samaritan Snare" some two months prior. Several reviewers re-watched the episode after the end of the series. In 2011, Keith DeCandido watched "Shades of Gray" for Tor.com, and admitted that he hadn't seen the episode since the original broadcast. He said that it was a "trainwreck" and even worse than he remembered, because other shows such as Xena: Warrior Princess and Stargate SG-1 had since done much better clip shows. Michelle Erica Green in her review for TrekNation called the storyline "absurdly flimsy" and that the episode "just felt lazy on every level". It was also the original choice of worst episode by Empire magazine, but it was decided that it didn't count because it was a clip show – so "Masks" was chosen instead. In 2016, fans at the 50th anniversary Star Trek convention voted "Shades of Gray" as the fifth worst Star Trek episode, of any series, and the second worst episode of this series, with only "Code of Honor" faring worse. In 2017, this episode was rated the 7th worst episode of the Star Trek franchise up to that time, by Screen Rant, and explained several issues with the episode including a lack of meaning in the clip segments. In 2019, they ranked it the 6th worst episode of the franchise based on IMDB rankings. Ars Technica and ABC News Australia noted that "Shades of Grey" had by far the lowest IMDb rating of any episode in the franchise. Ars Technica pointed out it had been "hobbled" by the 1988 writer's guild strike, and did not include it among what they considered to be the five worst episodes of the series. == Home media ==
