Fantastic epilogue. Seeing Rin and Shirou all grown up and acting mature, well, semi-mature(ish) was great. Going through all those scenic locations, getting to see Clocktower and all those character cameos, it was like an entirely different show on it's own. (One that I wouldn't mind watching. Looking at you, Type Moon)
I was half expecting to see Luvia but never thought they'd actually give her some definite screen time. And seeing Waver again instantly gave me the chills. One of the temple brothers got a brief cameo too which is nice.
The show sure had it's rough moments but I'd say it managed to live up to the mark. Fantastic way to the end the series and probably enough to warrant hype for Heavens Feel. Good show, Ufo.
