Is Back to the Future a perfect movie?

So I just rewatched it and I started wondering if the movie is technically perfect. We learn so much about doc brown from the very simple pan through his office. So many call backs to important moments and figures that reappear in the past that initially seem like world building. The juxtaposition of the present and past times, the soundtrack, the building of tension during the initial chase scene. Everything is pretty much perfect.Is there any glaring issues with the movie that my brain has ignored. I should point out that I'm not really considering the story as I know there are some issues with that, but instead focusing on the technical aspect. via /r/movies https://ift.tt/1Ol4Y8f
