SPOILER WARNING !! READ AT YOUR OWN RISK
Well , as a fan of the X series I must say I was really disappointed on this .
Mainly because they tried to fit all characters and a long and intricate story and character relationship in a 1:30 hour anime . There's only a blink of what is going on in the story , if you aren't familiar with it you won't understand anythiing at all and even if you do know the basics about the series you'll most likely be puzzled on how they shoved the story aside and turned this into a bizarre 'ending' for all characters showing what I believe to be the 'last match' between them and most characters end up dead one way or another . If you like the X series watch the TV and OAV instead .
