They are going way too fast, and they skipped important scenes or added innecesary, for example.
If you care, read the manga and compare the scene when he remembers his family when he comes back to the inn and hugs whit the other characters. You can see the diffrence of the emotions and the meaning of that part (as it has a lot of impact on Ryoma).
I know that it isnt the first time this happened but if we compare the 2, we can agree that the original is faaaaar better.
The characters also have been changed not too much but the relationships feel rushed and they are sloppy, and the environment/atmosphere is not defined (or defined poorly, in my opinion) and it is confusing, and makes me uncofortable.
As i said before they are going too fast. This is why also there are a lot of holes in the script,
