I read this article a few days ago and I agree with what everyone had said about the article itself and how it was constructed. It didn't help matters that the person who posted it on a different message board posted the link to the second page so I ended up reading that first and being more confused. It was absolutely poorly written and constructed. It does a great disservice to Max, Laura, and the show itself.
And I don't have a problem with Max questioning Sandy's big change at the end. And for all we know he did delve deeper into the issue but the writer simply chose to not include it. Maybe what Max had to say was too cerebral for what the writer had in mind. We don't know the answer to that.
In fact, I discuss the "moral" of Grease practically every day at work. I have to discuss High School Musical a lot at work and people are always making comments about how it's "this generation's Grease". And then someone else makes the comment about how High School Musical has a better point than Grease. Grease is about changing to fit in while High School Musical is about NOT changing.
One more point before I go. I went through a point in my life where I was Grease obsessed. But as I grew up, learned, and gained life experience I realized I just didn't like it as much anymore. But when I loved it my father was always telling me how much he disliked it. It actually used to upset me when he called Sandy a "jerk" for doing what she did. He said she went from being a "nice girl" to a "jerk". My father would have been in high school at the time Grease took place so this was a lifestyle he most likely witnesses and he had a very strong opinion on the lifestyle and the film itself.

We must have different Gods. My God said "do to others what you would have them do to you". Your God seems to have said "My Way or the Highway".
