As a whole, To Your Eternity initially does a solid job at presenting such events and ideas, from what I have seen of it in the past, it plays well with this whole journey concept it has going for itself. It doesn't feel half-hearted, the characters are believable, and for the most part, it was something to look forward to as you sway your way into the oncoming episodes. This, however, is true until it isn't. The latter half of the story sure goes on the same initial path as the first, however, with a substantial objective of the former half somewhat achieved (basically intelligence acquired), the story had to drive itself around a new fundamental for storytelling, which it did, but the result was lazy writing. It was evident that the writers didn't even try to fish out new ideas and instead resorted to "generic" ideas, generic isn't bad, but I'd say a poor shift is. The characters themselves felt like they were for the wrong demographic too, with random shounen-esque ideas coming for the sake of "there was nothing else to do", when in fact, the initial dark side would come and go when it was conveniently called for. It's a sad downfall, but it isn't one of a catastrophe, just one that didn't hold up to what some could consider an "initial lie".
The audiovisuals are relativity consistent, you know, they looked nice and sounded good, as they should, the general. That is until the latter half where if you are astute, you'd notice the drop in animation quality, it shouldn't hinder overall experience, in fact, it will only hinder if you care about it too much, however that is not to say it passes as a fault in my eyes. Maybe there were some background issues going on around this one, I don't have the information on me to come to such a conclusion, but considering the work ethics of studios, I think an educated guess shouldn't misinform people too much, though it's not like that's directly related to the final product anyway.
Overall, it's a fun and interesting experience, that had its faults, sure, so much so that I could not possibly call this a masterpiece or those other fancy words I am too dumb to understand. The anime got me thinking about the themes it had for itself, mostly relative in its anime universe, not superimposed onto a reality. But it does get you some thought as to, what you would do if you were in the same position. Is immortality a blessing or a curse for humans? Well, that's for another time.
