Rather lackluster. Nothing outstanding or memorable. There was virtually no character development, very little dialogue, it was all action and nothing else. And even then...the ending was pretty anti-climatic.
The series, and the characters especially, had so much potential and it was all wasted. The idea of these wicked awesome mutant children running around with so power at their disposal, and them being willing to use it wisely, was very cool. But nothing was done with it!
