More on the lines of completely different remake. It's simply called 'Negima!?'.
The art is a hell of a lot better than the first one and the opening is done ok as well. Only thing is, the story is completly messed up, never follows the manga in any sense (and only rarely too) and skips WAY too many chapters and plots. Go to www.animenewsnetwork.com for more details. Anyways, this is just a totally different view and I prefer the manga as both anime are never as good as the manga.
Like they already talk about the provisional contracts in the second episode and the story is accelerating WAY too much with things left unsaid.
Actually, they do so because there is a leap of one year. Smart move, actually - saves the watcher from stuff they already know. The anime is made for a japanese audience, for once.
