Did JP I have a plot? I failed to notice. It did have an extended chase scene. I guess that is what passes for a plot these days.
I will watch thes movies for the special effects, but that gets old after a while. I would watch them more times if they abandoned the pretense of having a plot and just let the dinos run free.
As always with Speilberg most of the plot got edited out in the second draft, but they kept some of it, more than they kept with 2.
