So I have 2 Negima DVD Collections, one is spelled as *Negima!* and the other is *Negima!?* with the latter also having a second DVD called *Negima!? Spring and Summer Specials*

Both have relatively the same plot summary on the back of the covers, both have the same number of episodes and [Anime News Network](http://www.animenewsnetwork.com/encyclopedia/anime.php?id=4380) just says that *Negima!?* is an alternate retelling. But what exactly is the difference between *Negima!* and *Negima!?*
