The first two parts are wild and super ridiculous (The first part is meh). The third part is more normal but still bizarre. The 4th and 5th are much more normal with much better writing imo. I rate them all 8/10 except for the first part obviously. Some fights and characters are so fucking epic that I would advise any shonen fan to at least give it a try. Watching the first season (part 1&2) will tell you whether you will like its ridiculous and bizarre nature or not. You really can't judge it from the mediocre part 1.
