Also, to all who are saying things about dubs... if you don't like the dub, DON'T WATCH IT! Yes, I agree that most dubs suck but you don't have to endlessly complain about them.
Leaving the dubs behind, Negima!? (not to be confused with Negima!), anything that's reminds me of Negima!?, and I could not watch more than 3 minutes worth of Natsu no Arashi. I would like to add than the Manga Mahou Sensei Negima! is one of my favorite fictional works of all time (thus far) and that while the ending was disappointing I found the first Negima! anime to be okay. Despite the fact the graphics were better and they were (for the most part) the same characters I still found Negima!? to be the worst piece of **** that I've ever seen and I would not watch 1 minute of it to save my soul from eternal damnation. Thank you that is all.
