I remember watching this at around 8 years old and not getting past the hour and 20 mark because I got so scared. As an adult, who's since attended film school, I can watch it in it's entirety and be completely blown away. It's a surprisingly emotional movie, and the CGI still holds up 17 years later, which lends itself to incredible set pieces and an emotional connection with Kong. It really is a tragic movie, and on that I think could be released today and no one would bat an eye at the special effects. They're that good.
