Some people consider the trilogy as one whole unit. While others are able to distinguish them as separate movies. It's just how peoples' brains work sometimes. Some prefer to think of the LOTR trilogy as one giant movie. Same with Star Wars. Matrix was meant to be one long movie by the Wachowskis (sp?) so that is how some think of it. I, personally, separate them out because I've only seen the first two. Never saw the final one. After seeing the second one, I decided not to finish the series and ruin the original. It took some time, but I finally blocked out the second one and now consider the original as the only movie. But it took some time.
