I mean, there's rough moments, but like most classic Shounen anime... the ultimate message is that the power of friendship will always come through.
it's an especially good show for the specific purpose that it's about a thousand episodes (more, but some of that is filler)... and counting. So if you need background noise while you work from home, you can go on this wild ride where characters have ridiculous, silly super powers (like the guy who ate the fruit that turns him into a giraffe, or the guy whose sword ate the elephant-elephant fruit), and by the time you run out of episodes, you'll have a backlog of other stuff to watch.
okay, that's not for everybody. but it got me through the pandemic nicely.
