TL;DR: The show so far has been pretty good so far, and I think people should give the show a chance. It's been episodic so far, so if you are a fan of episodic anime, you will probably enjoy this. If you aren't a fan of episodic anime, I definitely recommend you give the format a chance. I don't think Trigger will let you down come the end of the series, for more details read my full review.
I think it is a little early to be giving this show any sort of long-term judgements. I think those with negative reviews should wait and see if the series gets better, and I think those with overly positive views should not be blind to the problems apparent so far with LWA. The viewer is given little to know where the plot is going, and depending on how the series deals with this and changes in the future, my opinion of this aspect could change. Right now, I think it detracts from the story, but maybe it won't when viewed as a whole. The animation isn't anything crazy, but in my opinion, it has a great art style, appealing aesthetic, and character design. The sound so far has not been exceptionally memorable, but the soundtrack definitely fits the feel of the series. I just feel like it's not very memorable because it's the exact kind of music you would expect from this kind of series. Besides the plot kind of going in not apparent direction, I'm overall really enjoying this series, and I think anyone can really enjoy this series if they can get used to the largely episodic format the series has taken on so far. I'm personally a fan of episodic anime (The Tatami Galaxy, Cowboy Bebop, Gintama, etc.), and I think if you are someone that is okay with the episodic format, you have the ability to really enjoy LWA. So far all of the episodes have given us fun adventures into the world of Luna Nova, and I think most of the episode plots have gone in really interesting and entertaining directions. Personally, I was hoping for something not as episodic from Trigger, like how they did with Kill la Kill, but I still have hopes that Little Witch Academia will get better and better as the season goes on.
