Texhnolyze is certainly a difficult anime, as you see it the story becomes more serious and it becomes clear with every passing episode that the conclusion won't be a happy resolution. And yet that is the hold point of the journey, here you have a show concerning the transformation of the human essence once the pick of the race has long past. The cast are here to represent different aspects of our species and in their different arches will see how something new will be born.
Now that right there is where most people that i know say lies the reason why this show cannot be for all audiences, and here I disagree. First let me say that the only prerequisite is that you have more than 21, if so even if you do not like this genre you have to watch this anime. This is mainly because the scope a spread of the ideas presented are enough to justify at least one complete view of the episodes once in a life time.
The subjects tackled will expand greatly any set of values and at least force some revising of one's beliefs, and such a confrontations with once self will open new forms of thought.
So to end, watch it at least once regardless of personal preferences.
