Higurashi's pacing was fine for the first two arcs (the end of episode 8, brrr), but afterwards it gets way too fast and compressed. They shouldn't have tried to squish 6 full arcs in a single season. Though I guess it's not coincidental that I discovered Onikakushi and Watanagashi by the anime but discovered the other arcs in VN. The overly fast pacing stood out much more to me after I read the VN.
The second season was admittedly better, mostly because, well, they only had the last two arcs to animate (and they fixed the broken animation and twig-limbed character models too).
Well, you could say they at least tried to give the Higurashi anime its own style and horrific effects, while the Umineko anime seemed like they actively tried to suck out the intensity from every important scene. I'd love so much to see that anime remade, even if Chiru is pretty much impossible to adapt. =[
