First of all: No, I didn't watch the american version of this show so I might be totally wrong with my assumption.
But from what I've seen through trailers and coincidentally zapping to the show when it was on tv, the american version didn't catch my interest because in my opinion they focused too much on his special abilities as a doctor and his "geniusness" and less on the negative aspects and prejudices which an autistic person has to deal with on a daily basis.
And this version did a very good job depicting that. Because lets be real: society is not easy to deal with and unfortunately many people are bullied. And yes, doctors might be of high status but in the end they're still human so even though it was hard to watch, I don't think it's unrealistic that even between hospital employees and doctors specifically there's a lot of jealousy and mistreatment. And it was important to make that clear.
Also, I liked the many side stories about the little patients and getting a glimpse of their lives and problems and learning their stories and what brought them to the hospital.
What I didn't like was the whole (very typical) side plot about the hospital business itself and chairmen, businessmen and foundations fighting over the hospital. It was actually quite boring and unnecessary. They should've only focused on the main plot. That would've been enough if you ask me.
The ending of the show was quite satisfying, though a little too positive and happy go lucky in my opinion. Even the majority of the people who were like enemies throughout the show suddenly were on the pediatric team's side and the ones who weren't just weren't shown on screen anymore. I like happy endings but at least make it realistic.
All in all, I didn't regret watching it.
Conclusion: nice plot, very inspiring characters (specifically the patients), a few boring scenes in between.
