Say what you will about the musical numbers and plot, but from a technical stand point this film is very well put together. Everyone may look too old to be in highschool, but you can easily buy them as the charcters they are portraying. As well, the set design and colorful aesthetics feel genuine and believable, at least in the moments where they are supposed to. Overall Grease feels like a time capsule, be it for baby Travolta or just the re-created 50's. The story itself unfortunately doesn't really interest me very much, however I certainly can understand why many view it as a classic.
