I'm one of those people who enjoyed it a lot. I can see why you dropped it though, the characters may seem archetypal in the surface considering the plot-driven storytelling, but they actually have a lot of depth, and while the Arakawa manga did well to capture that (at the expense of a really, really slow pace, but it actually works for its kind of story), the anime kind of didn't do it very well.
As an example, Silvermask might only begin having in-depth exploration of his character by Season 2, but there was already so much exploration to his character in the manga early on, especially considering how far the manga was left behind story-wise. :<
I'd actually like to recommend the manga if the story is your thing. It had better character interactions and exploration, and a more solid storytelling in general, but if you already found the pacing of the anime to be slow, I don't know if the manga's pacing will work for you though. Also the manga art was inconsistent at first, but it's actually improving (unlike the anime haha).
