I read through it all. I think the series has a really funny premise, and at least the first half of volumes are really great at constantly introducing new characters (and challenges). I think where the series starts to get dragged down a bit is falling back onto the same punchline, especially when you've grown to like to protagonist so much, and have heard the same joke so often. Still a really fun series, and something I'd recommend. Some people don't like the art, but more than anything I found it really interesting to look at and very unique.
