Gave it an 8/10 myself. I'm extremely excited to see Umineko in anime form, at long last! The first episode did feel a bit too rushed, otherwise I probably would have given it a perfect score. On the other hand, after reading some comments on here, I can see why they wanted to get all this into the first anime episode. Leaves more room for the rest of the events of this arc.
I saw the bleeped version of the raw, and they were so jarring, it made me laugh my ass of. Husband thought I was crazy.
Overall, I was impressed and can't wait to see more!
