Magnificent Computer Graphic Imagery and Cinematography
claudio_carvalho21 May 2017
"Beauty and the Beast" retells the Disney's version of the French fairy-tale written by Gabrielle-Suzanne Barbot de Villeneuve and published in 1740. The story is very similar to the magnificent 1991 animation and highly attractive. However this 2017 version is uneven, with the most boring songs that anyone could imagine and reasonable acting despite the great names in the cast. But the top-notch Computer Graphic Imagery (CGI) and the cinematography are worthwhile watching. Keep awake along the musical scenes and you may like and be surprised by this version. My vote is seven.

Response: This version of the story is uneven with boring songs and only reasonable acting.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Good food but disappointing service
janedoe89 August 2021
This restaurant has a diverse menu with delicious dishes that are well-prepared and flavorful. However, the service is a big letdown. The staff is inattentive and slow, resulting in long wait times. The ambiance is pleasant, but the overall experience is negatively impacted by the poor service. Unless they improve their service, I cannot recommend dining here.
