I did not really find the story of Shukufuku no Campanella all that good. At first it seems like a lighthearted fantasy story that one falls in love with for being charming, but halfway through it tries to become a story that leads up to a final showdown, which just didn't work with this series. It also had one of those annoying endings with some lame sappy morale that all of the characters learn in the end and then everything is peaches and cream from that point on. I thought the ending was extremely lame. Some of the jokes seemed to be too repetitive, and I thought that the ecchi moments early on in the series were totally unneccesary for the type of show they were going for.
The animation was nothing really to complain about, but nothing really to like either. The one consolidation that Shukufuku no Campanella has in the animation and art department was that some of the action sequences did look somewhat nice, but other than that, It was nothing to make one watch the series.
There were some moments when I liked the characters, but there were other times when I did not like them one bit. Some of the supporting characters were a bit flat and weak, and I found every freaking girl in the series undying affection for Leicester quite annoying. If I had to pick a favorite character though, I would have to say Agnes because she is the only cool character. Leicester is all right, but nothing to rave about. Leicester's fangirls were just downright annoying. Minette was very naive, especially towards the end of the series.
I did not find Shukufuku no Campanella all that entertaining, but if you are looking to blow some time then you might want to watch it, but there are so many better things to do with ones time.
