The VN is perfect the anime is not. And it is in certain decisions.
Still have yet to properly read (or rather watch the let's plays) of the VN, have only seen a lot of snippets and read about the general routes structure along with a batch of spoilers so far - I think the directing is still were the Anime does fail chiefly. The Anime seems to have some a huge bunch of diffrent worldines and tries to show something of all of that, but most importantly fails to differentiate that visually. (Episode 8 and parts of the last episode had some hints of at least trying.) I wouldn't even mind the omissions of all sorts of plotlines, when it at least plays with the confusion. (And especially with S;G 0's plot were the point is having myriads of tries of several people messing with the timeline and not even Okabe knowing about all of them the story has every excuse to even have that confusion and seeming discontinuity in the chain of events.) It's not like the original Anime didn't have a hand for psychodelic imagery...
(Actually it would already have just helped to put in some divergence number in between the rooftop, the war scenes and that military base phone call.)
The shortcomings of showing Okabe's depression is also something that the visuals totally fail of putting good emphasis on. (Like his pills, 2 frames and it never gets picked up again. Or his red pen, I didn't even realize it was the supposed to be the same as his precious on the white lab coat, until somebody pointed it out.) Doesn't help that episode 23 Beta archieves more characterization than the whole S;G 0 Anime just in visual cues. =/
(I'd love to know what it was that cause the divergence of director Hamasaki not picking up S;G 0 after 23 Beta. Is it the Orange Anime's fault? Or whatever he's doing now after that, as there is no info on that either...)
But for all what I've seen from the VN the collective breast operation all females must have undergone seems to be something huke's latest artstyle is responsible for. And the the aforementioned groping and military-cleaning Nae seems to hail from the VN as well. And let's not talk about that scene with Maho...
(Really, from his vast list of serious compositions It's obvious Jukki Hanada knows better than to pick scenes like this out of all things. Especially when A place further than the universer went on air the very same year and that script is flawless. Who was that entity who must have put him under a whip and said this, this and this fanservice scene must be in there? Probably the director again?)
