I was hoping for this OVA to get me back into Higurashi after the longest time, guess I'll just echo what's already been said and say this first episode didn't feel like Higurashi at all to me. Mostly just boring perverted pandering and uninspired unfunny humor.
I'll admit it's nice seeing the characters again in something new though. Some of the most significant figures for me during my time as an anime fan.
Preview for episode 2 makes it look to me like it could go both ways, be either really cool and entertaining or a total waste of time. It doesn't look very "Higurashi"-like to me either, more like some spoof of Madoka Magica, but I'll judge it as it comes.
I'm hoping there's at least one of the planned 4 episodes that re-captures the essence of Higurashi. If there's at least one then this OVA series will be worth it.
