Why JP3 wasn't As good

It's certainly entertaining but in my opinion there were a few things wrong with it. One being the CGI, it strayed from the beautiful animatronics created by the great Stan Winston. This made most of dinosaurs come off as unrealistic, making it feel like they were pasted onto the screen. Character development is another minus, it would never be as good as the first,but none of the characters really grew served any purpose other than being eaten. Third and probably most important is the story. No on is really going to believe a preteen is going to survive on his own for months on an island filled with dinosaurs, and living off of Nestles crunch bars. He would've been dead and still attached to the parachute. Another thing that bugged me was the raptors lack of aggression. In two scenes they stared way too long at their prey not to do anything, and in the final one they just let them walk away... Amazing. To top it all off ,the rescue scene at the end was just a perfect summation of the over the top story that was just told. I've been a fan since I saw it come out when I was a kid, and I love the whole series really. Just wanted to give my thoughts on why it didn't really hold up.
