I did not see The Sixth Sense until its home video release later in '99. My brother was home from college for the holidays and he brought the VHS to show my mother and me. I was 13. I was thoroughly engrossed in the movie and blown away by the twist. It was a lot of fun.
Of course, I saw The Phantam Menace three times in theaters that summer. Fox went all out on the promotion for it. Remember the teaser poster, with Jake Loyd's shadow in the shape of Darth Vader? I thought that was so cool.
Austin Powers and The Matrix are true pop culture icons of the '90s. Everybody could quote those movies, even if they hadn't watched them. I saw the Spy Who Shagged Me with my best friend that summer and we laughed our pre-teen heads off.
