Grease: Rise of the Pink Ladies already corrected a problematic theme from the original film. Grease was a massive success when it was released in 1978, becoming the highest-grossing movie musical at the time. Despite coming out in 1978, Grease shared some outdated morals with its 1959 setting. The new series has a modern perspective and focuses a lot more on female friendships than romantic relationships. The show takes place in 1954, but the characters have the mentality of women from the 2020s, making it more appealing to the new generation. Though Grease remains beloved, one storyline specifically wouldn't work today.
