I can understand that somebody don't like the New Mutants characters but i don't think lot of people share this opinion.
The original run of NM was great (i mean until Lefield messed up everything) with really appealing characters, not that powerfull and reacting like normal teenagers.
Since then, few of theses NM got a real chance to shine except Cannonball and Wolfsbane. From my point of view, only Rahne benefited good development thanks to Peter David mostly.
NM vol3 was great until Zeb Wells was replaced by uninspired DnA and then canceled. Again, it seems that theses characters are doomed to limbo.
Recently, Magik has leading role in UXM but with poor characterization, like she's just a good substitude of the blackbird !
