The 80s were an optimistic time. People wanted to believe in the promise of the future. A lot of what was produced during that time presented a better life for all within a few decades. Teen rom-coms were ascendant and they always showed the story wrapping up with a happy ending. Sci-fi had a mostly positive way of looking at how things would turn out. Back to the Future 2 comes to mind where it showed how 2015 would have flying cars and self drying clothes and so many other things. Bill and Ted's Excellent Adventure and the sequel Bogus Journey are perhaps the pinnacle of this type of optimism.
