So.... The 4th season of Zero no Tsukaima, and let me tell you why I scored this so poorly.
All through out the whole series Louise has not changed in any aspect what so ever. She still goes on with the same routine, "oh I'm going to trust Saito from now on" and ends up frying his ass at least once in each episode.
This season would have been some what bearable if Louise had some character development, but unfortunately that is not the case.
This also goes for the other characters as well, almost NOBODY has really developed through the series. Because of this each episode is just the same thing over and over again, and to be honest I'm sick and tired of it.
