On rewatching a movie

Every time you watch a seminal movie you have watched earlier, the experience is different. You already know what's coming in a particular scene. That gives you the liberty of focusing on things you never noticed in the earlier viewings.
You finally understand that mumbled dialogue.
You finally see how much attention has been paid to detail in the story. And how much attention has been paid to rendering that detail in the movie.
Or you can just focus on the soundtrack, and notice how it complements the story. Keeps the script on its toes.
You can savour the scenes you like again and again. Brace yourself for the thrill.
You can look forward to feeling the goose pimples again as he gets ready to jump from a Hong Kong highrise, and soar like a, yes, bat.

Seminal (adj): Containing seeds of later development.
