I started watching EAW with really high expectations caused by the praises all over social media. I enjoyed the first few episodes. The characters were likable and there weren't any plot holes. The story went on smoothly and the acting was also good.

That saying...
Because of the one-case-per-episode structure the drama felt repetitive. That could've been fixed by spending more time developing the characters. They weren't explored enough, we don't know anything about them, especially LJH. Instead of being a main lead, he's more of a main stranger. The only thing we know about him is that he's respectful and popular among his colleagues.

The one character that was really shining here was Jung Myung Seok. I really liked him. But again, his story wasn't developed well enough. The writer really brushed over the seriousness of his health problems. His family struggles were also overlooked. We couldn't follow the process he had to go through in order to solve the problems. It wasn't shown, there was just the starting point and the end result.

I wasn't gripped by the FL's character. Of course, I reflected on the way autistic people are treated in society and their struggles in a daily life while watching the show. However, I'm not sure if that's enough to make this drama interesting. Maybe it would be better if there was one bigger case and we could follow her struggles and her thought process while solving the mystery, instead we got small unconnected cases.
That leads me to the thing that I grew tired of -

that one editing trick they used all the time to show that she's just had the 'eureka' moment.
It was like telling the same old joke for the umpteenth time.

In conclusion, this is a solid drama, probably one of the better ones. The experience should be better if you watch it casually, one or two episodes per week. I don't think this drama is meant to be binge-watched. However, I think series should be gripping regardless of the frequency you're watching it with.
I was a little disappointed because the social media shot my expectations through the roof. In reality it's pretty good.
