Even after decades, the 'Back to the Future' trilogy is an enjoyable and adventurous ride, and belongs to the few time-travel movies which have their time-travel logic intact.
This first part is innovative, intriguing, and a funny all the way. The writing is efficient and tries its best to not leave any space-time loopholes (neglecting small details and related consequences, and other goofs). Good acting from everyone involved, and effects (the minor instances it's used). The entire prom sequence is just brilliant. It was a wise decision to take the story to the past, which saves a lot in special effects expenditure. I don't think I need to say more; it's a sci-fi classic now.
Spoiler: It's sad but not paid attention to; no matter how his parents were, the parents he returns to aren't the same people who brought him up. Was he just happy to have this new enhanced version of them? Yes, getting rid of the bullying part was completely fine, and I agree that the new versions of them are much better. But the rest? The memories he had with them don't exist anymore. Anyway, that part isn't a big deal; maybe we aren't supposed to analyze that aspect so deeply. And why did it have to end in a cliffhanger? The next part didn't come out until 4 years later. It's still a hilarious cliffhanger, though.
