Ahead of its time!!

Rating: 9/10 (4 August 2019)

I saw this movie at the theater in 1999. Awesome movie I'm almost every way. I recently watched it with my 10 year old daughter and she absolutely LOVED it as she is into sci fi. I cannot figure out however why it's rated R!! I feel like it should be PG-13. What's with the R rating? It's not like it had major language or violence and gore.. it had no sex or nudity either. Just unsure why was rated R but whatever, still a great movie. Can't say I remember 2 and 3 that we'll though
