Your argument seems to boil down to you enjoying the source material and being a big fan of it. As someone who has played a little of the source material, and read a TON about it I seem to like the UBW adaption more than DEENs, precisely BECAUSE I have barely played the VN...but from what I have seen, I don't think I want too...
I found the VN bogged down in the pairings and weird harem aspects that unfortunately remind me of SAO. Its sexist too in its treatment of the female characters (if the author has to say that he is going to try harder to write better women…I think that speaks for itself). So if UBW TV takes some liberties here or there, okay…I am fine with that. If people wanted something just like the VN, PLAY THE VN. I have no comment about the music, except that I honestly see both equally. Because, again, I don’t find any tracks memorable from the original. Fate/Zero’s soundtrack, despite sounding the same for a lot of songs, was better than both IMO. Additionally, UBW has Aimer…so yeah
I disagree with that assessment that everything stops when they focus on the characters. The only episode I can think of that might be guilty of this is episode 11 of season one…but then, the DEEN adaption had an episode where Shirou takes Saber out on a DATE. For no reason except…shipping? That far exceeds anything UBW does...and I know you will probably make the argument about the necessity of that episode in the DEEN production. But then, so could I in UBW…It seems to me that the Visual Novel just stops everything so the characters can have "romantic moments (you know what I am talking about)", which really makes no sense given the situation a lot of these people are put in.
And I have no idea what you are talking about a 'whimper.' The summoning of massive swords to throw at Shirou, mixed with the emiya theme (omg, I think I am starting to get the love for that song), and the lighting of the Blade Works with clear blue skies was great. Better than the movie where Shirou’s responses were, “Right will always defeat wrong!” Which isn’t really an answer to what Archer was saying; whereas in this version, Shirou’s answers to Archer make sense and explain why Archer gives up. And although it was less flashy and quick, I found the meaning behind the artwork in the finale between Shirou and Archer far more dramatic and emotional.
Huh…where did I say I think ufotable will do a movie better? I know it will be rushed and probably leave a lot of stuff out (if it is just one film). Just because I like this adaption of UBW doesn’t mean I think ufotable is perfect (I am still mad at them about movie 6 of the Garden of Sinners). I think they are doing a fine job with decent source material that showcases the strengths of the Fate franchise. And hey, I actually don’t hate Shirou in this version! He is tolerable! And his “I protect women, because women cannot protect themselves” is toned down and almost nonexistent!
For 2000 years I lay dormant, now I have returned to bring good cheer to you all once again!
