I have followed the manga since its very start and have enjoyed it very much. I'll stretch out as far as saying it is a masterpiece, ranking as one of my favorite mangas of all time. Then there is the anime.
As you have already noticed, I'm already annoyed how the anime turned out. I'm gonna rip and analyze one point of the time, and we're gonna start straight on...
Keima: This is the main character. He is, as the title implies, a God. The God of Galge Gaming, or that's at least what he should be. In the manga, he was bitchin' cold to everyone else and showed no interests for real girls. Because 2D-girls was his thing, due to his world consisting ONLY of galges. So when he got forced by Else to do all the captures, he simply accomplished his tasks and moved straight back to his galge gaming. He was asocial. The forced tasks were simply business with no personal emotions attached. This made him cool, or perhaps even godlike because he was unlike any other spineless romance comedy main characters. This coolness aura was completely swiped away when he fucking BLUSHED IN THE VERY FIRST EPISODE OF THE ANIME. That might sound trivial to you, but that single element alone killed his cool personality. He was reduced to yet another one of the countless male main characters in comedy romances who blush by every little thing the girls say. He was made weak, and it ticked me off. And also, it doesn't help when he has the voice which sounds like every other pussy male main character in comedy romances. By the way he acted in the manga, which is in a godlike, intelligent way, he should have gotten a voice that corresponded to those characteristics. Maybe something like Lelouch (that's not a perfect match, but you get the idea). But back to the blushing. Keima blushed for the first time far into the manga, and that signaled a character development. But since he blushed in the very first episode, he would receive zero character development. Luckily, he wasn't totally stripped of his personality. One example of that is that he is still gaming most of his time in the anime. But that alone isn't very redeeming.
Fillers: Really? They had 12 episodes to go on and they dared to use three episodes for fillers. That's just a fuckin' waste when you have shitloads of chapters to use from the manga. I DO NOT WANT TO SEE AN ENTIRE EPISODE DEDICATED TO ELSIE. GOD. And if that wasn't enough, some of the episodes with content from the manga were unnecessarily stretched out, like the Kanon-arc. You know what? In the first chapter of the manga, the first girl Ayumi, kissed Keima of her own will. But in the anime, they fuckin' "accidently" fell down the stairs and that resulted in a kiss. That is one of the very many cliches the mangaka wanted to avoid, and here it is in the anime. I suspect that all these decisions on fillers, whether on a smaller or bigger scale, were aimed to please a specific crowd of the audience. And for that, I hate.
Voices and sound: I've already ranted on Keima's voice, so we'll leave that be. However, all the other voices were as I had imagined in the manga, or at least approximately, so that was good. I wasn't too fond of the OP, though. I applaud for making it different than your average comedy romance OPs. I liked the ED more, as it was imaginitive and colorful.
Other than that, they followed the story fairly decent. In general, I liked the animation and the colors the studio went for.
SUMMARY: Fillers, fillers everywhere. Okay, not everywhere, but I had to pull that meme out. Keima was the pillar of the series, and because his personality got butchered, the anime fell apart. Go read the manga. It's so much better.
