Definitely not for small children
This show is rated TV-PG, and there's a reason it's not Y or G. The show mirrors the events on Jurassic World, but from the perspective of six teenagers who are there for a camp when the dinosaurs inevitably get loose. Thefirst few episodes are typical kids show adventure stuff, but by the end of the series, there are people very clearly getting eaten by dinosaurs, even in they're not on screen. The children are in very tense, dangerous situations, and it doesn't have that feeling other kids shows have that everyone is going to make it out ok in the end. Only show this to children if they are comfortable with shows involving real danger, constantly growing tension, and legitimately frightening jump scenes.
That being said, if your child is old and mature enough, it's actually a pretty good show once it gets going. The main characters are diverse and complex, and there are good messages about teamwork, friendship, and acceptance of others. The tension and action are good enough to keep adults engaged, as well.
Also, at risk of a spoiler, the end of season 1 is a cliffhanger, not a resolution - so if you are looking for a happy ending, you might want to wait until the series is complete.
