Yeah, well I'm weird, I know that if they were paying attentions then it will probably not be missing any important stuff, but little things still bother me, particularly when it was not necessary (they could have just used the full 4:3 frame). For instance look at
this example. You can see that the frame is cropped at the top and the bottom.
Not being able to see that IV bottle/bag in the lower right corner next to the patient's head would really bother me even though it does not add much to the scene. What bothers me is that the director put that bottle in there and had it in the frame so that we could see it, but someone else decided I didn't need to see it.
If it was originally 4:3, remaster it in 4:3 at a higher resolution. If someone doesn't like the bars, they can just zoom in to the pic on their TV. They could have even made it wide screen without cropping the top and bottom, why not do that? (I'll guess that the film frame does not extend far enough unless they zoom in a little, otherwise still leaving black bars on the sides, although smaller bars than a 4:3 crop would have)
By the way, I generally don't watch sitcoms anymore, I just got tired of them, but my two favorite sitcoms of all time are MASH and Taxi.
