If you want to watch Monster Hunter, go to YouTube and search for some Let's Plays. The CG will be better in the game by far and the games aren't targeted primarily at children.
The major problem with this show, other than having some of the worst presentation I've seen, is that it has an additional 27 episodes after the initially planned 48.
For the 48 episodes, which shall now be known as "Part 1", that were planned out and made with some sort of nuance, there is a good amount of content for the kids. At the end of the first quarter in Part 1,
one of the main characters suffers a very significant loss and has serious problems dealing with this internally. A different main character also has to deal with a loss of their monster after fighting with a blighted Nargacuga. Both of these events have lasting impacts and are executed in such a way that is appropriate for children. Part 1 goes through the monster of the week motions, develops a rivalry with some characters, explores backstories and tries to have an epic structure to build to a conclusion. This is mostly acceptable, but unimpressive.
Unfortunately, the show didn't end here and continued until episode 75. What shall henceforth be known as "Part 2" is garbage. It was unplanned, it has no themes, and meanders along. The character arcs from Part 1 may have been fine at the time, but since the end of that, no characters progress whatsoever. They don't face any serious threat and the big bad is very un-scary. Unlike Part 1, there are no themes. Nothing about the loss of the characters. Nothing about rivalry, or ideals about owning monsters. Complete trash.
If you are under the age of 10 and like the Monster Hunter franchise, Part 1 (1-48) are perhaps worth a watch if terrible CG is tolerable. Skip the rest. There is more fun to be had watching mediocre YouTubers that can barely break 80k subscribers.
