The style of story reminds me of Deathnote, in that there is lots of talking and reasoning/mystery solving. However, if you liked Deathnote because of its plot's strongly analytical nature, you will be horrified upon watching this anime. I don't want to say too much, but let's just say it's no Sherlock Holmes (or Deathnote P:). In this respect, Umineko no Naku Koro ni is a big, smelly turd of an anime.
Now, IF (a very big if). IF you can look past a plot that doesn't make any sense at times, you will find a excitingly paced story that is always changing. Yet somehow, it resembles the original Higurashi's style as well. Everything else about the anime is pretty decent borderline enjoyable.
All in all, I don't regret seeing this anime. It wasn't the most impressive, but it wasn't too bad (except some elements of the story) either. If you liked Higurashi, and can look past some major story flaws in this one, there's a chance you might like this*. But just keep in mind that the two anime are not of the same caliber.
* I would watch up to episode 6 or so before deciding whether or not to continue.
