Mel never struck me as particularly intelligent - and that's not a slight nor confirmation that she isn't.
I just never got intelligent nor articulate from her. What I did get was that she often plays it safe, tiptoes the line and waits for where a consensus in the room will land before being agreeable. Now whether that's her personality or if she was conditioned by the environment is a different discussion.
She actually comes across exactly how I expect an attractive video vixen to come across - surface level takes on a lot of topics, not a lot of honesty/being forthright on a lot of topics, playing coy on some, and a compulsive need to be liked and treated as special. A chameleon of sorts. And to me it makes sense because from lived experience - anecdotally - that's how a lot of attractive women navigate life/work - especially one that made/makes a living out of the proverbial "male gaze"
