You've all got to keep in mind that on this recording she's singing the song at some fundraiser or event or something. It's not in any context, they just threw her up there (obviously with not much rehearsal) to belt high notes. Don't take any acting from this, because there really isn't any that's applicable.
KC, while your thoughts are welcomed, they are not being put in the right place. The comment was uninformed because Jennifer Hudson sang the song as it is supposed to be sung, and as it is written on the page. That is how the writers intended it to be sung. Everything in the score is written down including the riffs, the tempos, the dynamics, everything. If you do not like this version of the song, then yes, you don't like the song the way it's supposed to be sung.
The fact is, the comment WAS uninformed, because if they knew the history of the song, they would know that the way Jennifer Holliday sang the song, is the way the authors INTENDED and also the way they WROTE it. We're not talking about reinterpreting it, because that song is not up for reinterpretation.
And while you may think that Margo's comment was rude and unbecoming, you're not coming across too nicely, either.
