And I'll watch pretty much anything. , ASSISTANT: can u tell me a movie that fits that category, and tell me why u really liked it , USER: Yeah. The first Spider-Man movie, I thought it was a great movie. And it really got me hooked on superhero movies, because I thought the story line was pretty good. The actions, the scenes, the direction. Everything is perfect on that, and I think I've watched it like 20 times.
