For the first point, I feel that many people may be watching all kinds of BT versions online, and there is a problem with the translation of Chinese subtitles. In fact, the film makes clear the difference between hunting dinosaurs and killing butterflies by mistake. The logic of the plot is simple, but it's still in the past.
As for the special effects of the film, it makes people feel very strange. The special effects in the first half can only be described as appalling, simple keying, huge fake dinosaur models, ugly futuristic buildings and vehicles. Even Star Wars is more realistic than these; but in the second half of the time, the various monsters derived from the wave after wave of attack are obviously much more detailed and realistic.
In general, you can first have a general understanding of the plot of the film, and then fast-forward to the second half to enjoy.
