Having read the LN, it's really hard to judge the anime. Is it at least good enough to pique the interest of new readers? My experience as a LN reader is not a reliable barometer here.
Episode three is missing many, but not all, of the little character moments that I look forward to when rereading the series.
For example, it's missing the fact that Myne only learned Gustav's name for the first time at the restaurant. And the way Cornelius snuck into the meeting. And the rivalry between Liesse and Hugo.
But they included Rihyarda bullying Ferdinand. And Rozemyne's conversation with Sylvester before the Starbind. And Ferdinand extolling the virtues of consomme.
My sense is that it's missing more than it includes. But perhaps this is appropriate given the accelerated pacing. It's hard not to feel the misses more keenly than the hits. Unfortunately I just don't have any feeling for how well the anime is doing at telling the story while still providing enough of the unique little moments that make this series stand out.
