I own this on VHS, DVD, and Blue Ray.
Probably the single most influential Sci-Fi movie in history, kick starting the single most influential Sci-Fi movie series in history. The start of a legend in this break out blockbuster of the millennium. Well crafted, well written, and a whole galaxy of characters and potential.
The film isn't flawless, but it paved the way for two superior direct sequels, 3 underwhelming but overly unfairly hated prequels, a continuation of side stories and distant sequels, an innumerable amount of books and comics, and a ton of fun video games. There hasn't been anything so impactful in cinema since, and may never again.
Mistake Status: Have not looked, might in the future but not sure I can find anything new. But up for the challenge.
