I'm not going to differentiate b/t theatre or video b/c for many of them it's hard to remember, but I have seen 62 of these movies throughout my lifetime. And, for the record, I've liked them all for one reason or another. Many of them (Lion King, Jurassic Park, esp) are my all-time faves.
1) How many have you seen? 73
2) How many have you seen in a theater? 26
3) How many of those you've seen did you like? Most of them -- I didn't care for Independence Day, The Lost World: Jurassic Park, or Star Wars Episode II.
I've seen 76. I'm a real movie buff! I liked most of them, but I was disappointed that African Queen and Wizard of Oz were not among them. The Wizard of Oz is coming back to the theater, with the movie and soundtrack restored. After watching it every year on TV, I still want to see it in the theater.
