New member here. I was looking for other opinions on FSN, and I guess I came to the right place.
I was introduced to the series by a friend of mine, and generally knew the plot of the game from them.
Knowing that, there were definitely moments in the anime that I adored, and others that I found lacking.
Spoiler:
As far as character development, I have mixed opinions. For example, Rin, Shirou, and Saber are all very well defined, with the exception being that I felt Shirou's jumps in ability, albeit explained, happened too fast. Archer, IMO, is inactive for far too long and is eliminated without much being explained, only weakly implied. Lancer we barely even see, the same being true for Assassin. I had mixed feelings about the portrayal of Rider. At first, she seems like she is unwilling to follow Shinji's orders, as evidenced by her comments to Shirou when he discovers Shinji is a Master. Any of that is quickly wiped away is favor of having a stronger villain early on.
Character interaction were well done, specifically b/w Shirou and Saber and the supporting cast. Everyone else has distinctly individual personalities, although a few, like Archer's, could have been better defined.
Shinji's relationship with Sakura is never really fleshed out, and I would have liked to see that. I also think they made Gilgamesh far too reliant on Ea and Enuma Elish. Caster and her Master also have far too little time dedicated to them, and Kirei honestly felt like a surprise enemy, even though I knew the storyline.
Shirou's and Saber's romance was well done, I thought. I justified it by thinking that after the events of episode 14, Saber decided to be more natural around Shirou. The comedic effect was mostly welcome, as well.
I felt the animation was beautiful, and although I do deduct points for the varying quality during and after episode 14, it still seemed above average to me.
The fight scenes were mostly simple, but on the whole they were well done. The exception to this being Saber's final duel with Gilgamesh. It was less of who the better strategist was and too much of who could cause the bigger explosion.
Ultimately, I feel the series ended on a good note. I actually liked the way the bittersweet ending was pulled off, because IMO, it does leave room for a non-canon sequel. OVAs of the other storylines would be cool, too.
If I could change anything, the series would have 3-5 more episodes to aid in character and plot development, because the ending did seem rushed.
That, and I would have liked more consistent animation after episode 14.
Also:
-Shirou's UBW
-Shirou vs. Archer (It was shown in the second OP, but not in the anime. Why?)
