How to more fully enjoy the Back to the Future trilogy?

Watch the original movie.

(wait a week or two)

Watch part 2 and 3 back to back, or over 2 days.

Why? Because...

Part 1 release date: 1985
---
Part 2 release date: 1989
Part 3 release date: 1990

Great Scott!!!

Who cares? Well, there are a few inconsistencies between part 1 and part 2/3. I don't want to ruin it for you. Just enjoy and don't think too much.
