Best Episode of Season III
15 March 2012 | by (India) – See all my reviews

This was such an awesome episode!! First of all the character X23 is a dark one and I loved its origin and contrast to other mutant's lives. The way their training contrasted each other, really flashed the gist of her life in a second.

Then comes the suit, it was an Ultimate X-men suit - seriously cool.

But the best part was the action!! Wow, whoever choreographed the sequences - when X-23 skidded down from a sky-riser using her claws, when she attacked the Xavier mansion - Wow! Her fighting style was so smart and cool, improvising every second, taking advantage of everything and everyone nearby. Every second, I wished that this could be re-done in a bigger scale with live cast - wow, it would be enigmatic!! And to think, that she took out all the X-men herself, with Berzerker telling Wolverine - Even you couldn't take us all! Perfect adrenaline pumping episode for an X-men serial. Not that I hated other episodes - I really like the whole series, specially the chemistry between the lead mutants. But this was really something.

And the final line says it all about the message - Sometimes, you gotta let kids just be kids.
