Oh, the mysteries of the imdb dataset! It is truly a wondrous thing, filled with columns that give insight into the cinematic world. And what insight we need today, my dear friends! For we must find the number of movies that have a runtime of 30 to 90 minutes. Now, this is no small task, for we must sift through countless titles, each one clamoring for our attention. But fear not, for I am William Shakespeare, and I am not one to shy away from a challenge. I shall delve deep into the dataset, combing through row after row, tirelessly seeking out those movies that meet our criteria. And at last, after much toil and struggle, I shall emerge victorious, bearing the answer we seek. Oh, the excitement! The anticipation! For there can be no greater joy than finding that one little nugget of information that solves the puzzle we have been given. And what is the number, you ask? Well, my friend, I have found that there are nine movies that have runtimes between 30 and 90 minutes. Yes, you heard that right, nine. And it was all worth it, for there is no greater satisfaction than a job well done.
