No—I fell in love with seasons 1 and 2 of Crystal this year (I watched the finished products, the DVDs). I liked the art of seasons 1-2, the characters looked like they did in the manga, the anime felt introspective.
I wanted to see the 60 acts of the manga animated.
Eternal feels like a complete departure of Crystal, different format (movie) & aesthetic.
It's okay, I guess. Sailor Moon Crystal was trying to look like the manga, but to be honest, I don't think it really does (the style is still nice, though). It seems like the new style is trying to look more like the 90s anime. Either one is fine with me, what I'm more concerned about is the fluidity of the animation and how the keyframes look. The first 2 arcs of Sailor Moon Crystal had a lot of issues with that when the episodes first came out, but the 3rd arc looked really nice. As long as the animation of Sailor Moon Eternal is fluid and on-model - and the story follows the manga instead of retreading the 90's anime - I'll be happy.
I like it just as much as the art for Crystal seasons 1 and 2. I really appreciate the way Miss Tadano draws the eyes for the characters. I also love the attention to detail Ms. Sako had when it came to numbers of lines for each of the Sailors' battle uniforms. Overall, I'd prefer a mix of Tadano and Sako.
I can go either way based on the final products we got. I love how fluid motion is in S3, and it looks like we may get more of that in Eternal. HOWEVER... If every episode of the first 2 seasons had looked like the episode with Neo Queen Serenity running out to glare at Demande, I'd pick the original art style, hands-down. The first half of that episode is gorgeous and feels very flowy, like Naoko's art.
