Don't watch the sub, don't even bother, it's not worth it. Sub is 2/10. It has 0 redeeming qualities. Mediocre art, mediocre writing, mediocre sound design, mediocre everything.
However, the dub is a different story. This dub is a masterpiece. I didn't know it was possible for a bit of script changing to make a boring intolerable anime into something I'm willing to watch if just for the jokes alone.
Though, that's about it really. The jokes are really good. The dub changes the characters by giving them outright ridiculous character traits, which I respect since it does make everything more interesting, but the story still doesn't change, so with that said, if you want an anime to laugh at, this will probably make you laugh, but if you're looking for anything else, this isn't for you.
