I do think part of it is how much you are looking for things .... I know the first time I rode the new version I was in the middle and other than some bending to the Eiffel Tower I didn't notice that much as as for the CGI only one scene really detracted for me ...
... later, when I was more cognizant to look for such things and I rode on the side, I noticed a ton of distortion and more CGI and it really made it a lesser experience
I think if you go in wanting to enjoy the ride or not knowing about these issues you would enjoy it much more than if you go in expecting to be disappointed as then you will focus on the flaws.
Personally I think it is still a really fun ride, though do think it is worth asking to sit in the middle section
