As you watch the movie, just let it wash over you. You'll have a much better time than trying to figure out things like:
SPOILERS SPOILERS SPOILERS SPOILERS SPOILERS SPOILERS
the time line of having the partner and long-time friend of John Hammond from the original movie being basically the same age of Hammond but now twenty plus years later and having a ten-year-old granddaughter who is actually not his granddaughter being the cause of their "falling out" so many years before her creation;

trying to understand how anyone could think that a dinosaur, even a highly trained one, that can be killed by poisonous gas, tranquilizer darts, or bullets would make a good weapon;

that messing with the natural order is never a good idea;
why a T-Rex mus stand above it's prey and roar in the same exact stance after every kill;
making your own species of dinosaur is also not a good idea;
and neither is opening an amusement park on an active volcano...

You get the idea. If you think about anything other than the thrill that is Jurassic Park: Fallen Kingdom, you will find yourself questioning your judgement. Of course that is pretty true of most of the Jurassic movies.
Just sit back and enjoy. I will likely not buy the Blu-ray.
