Interesting that the S10 HD closing credits framing is now consistent with the S2 thru S6+ framing (which I prefer) than the one used midway thru S7 thru S14 (which is further away).
This is a very embarrassing mistake.
I do appreciate WB's efforts in remastering the whole series very much. This is the best news in years.
However, changing the background picture on those end credit cards is completely unnecessary. I think they probably did that accidentally, but it should be corrected because the biggest part of the target group of these newly digitized episodes and the blu-ray release are quality purists — and the top priority is getting the existing show (and not a changed series) in the best possible quality.
For that reason, I also feel uneasy about changes. I haven't seen it myself yet, but I read somewhere that WB eliminated the reflection of an assistant director in a scene. Of course, that reflection was an error in the original production, but it's something that shouldn't be changed.
I think I can be more tolerant when it comes to misspelled credits (it's probably okay to correct obvious typos) or frames that have been accidentally flip-flopped in the original editing, but changing the picture or details of a picture somehow gives me the creeps.
