As far as anime brawlers go this one actually is not half bad. It feels less janky in comparison to J-Stars and the Haki & Devil Fruit mechanics are interesting and good fanservice. Roster wise its pretty solid too although it is missing a few characters like Magellan, Arlong, and Kuro. Story wise it only covers Marineford which is a bit disappointing as I was hoping it would cover the whole story. Like pretty much any other anime brawler, it does get tiresome after a while but I didn't get bored of it nearly as quick as I did with J-Stars so I give it props for that.
