Review of World Trigger
World Trigger starts pretty strong if you can get past the first couple episodes. It has good world building and all the invasion stuff is very entertaining. It does... have issues, however. And they become very apparent in seasons 2 and 3. Season 1 also has a large pointless filler arc that didn't even get dubbed that you can just skip completely: episodes 49-63. The biggest issues are pacing and one dimensional characters. Characters also get very little progression and often end up repeating the same progression arcs over and over ad nauseam. Even when they finally seem to get over it and you're like "ohthank god, finally!" they're soon just thrust right back into it all over again for no apparent reason.
Once you get to the mock rank battles with completely forgettable characters I hope you like it (though I don't know how you could) because that's the rest of the entire show. Just that. Over and over and over and over. And over and over and over some more. And not just this season, seasons 2 and 3 as well. Season 1 and 2 you're like "yeah okay whatever, I get it, let's move along already" but by season 3 it just serves to waste your time and piss you off.
It's like the author ran out of ideas and just started spinning their wheels. And with only 1 chapter a month with two 2 year breaks in the past 5 years it's not made much progress even on the manga side.
If Naruto had some cool war stuff very early on then immediately went into the Chūnin Exams except all the characters are replaced with Character A, Character B, nameless forgettable uninteresting one dimensional characters and they finally complete it after a dozen episodes then just have to keep redoing it for the remainder of all of Naruto repeating the same progression arcs over and over, that's pretty much World Trigger. Though that's not even a great comparison because the Chūnin Exams of Naruto were actually good and its characters weren't one dimensional and were actually interesting.
It was promising but basically squandered.
