I love getting a chance at seeing the man behind the brill-creamed mustache. JJJjr Could be so much more, sadly too many writers give him a 2d personality. Honestly I loved the bits of characterization we see in "MARVELS" and the ocasional scenes like above that they just randomly throw places in the Marvel product line. Usually they are throw away scenes in some shitty stories but over all they are those character breaking moments that remind me why I like comics.
For example, there are some moments where JJJjr is actually hurt by Peter being spiderman. Not angry, not blathering on about lawsuits. But a couple good scenes where he seems genuinely hurt. While arrogant and a prick, JJJjr could be someone worthwhile to look at as a character portrait in a miniseries. An understanding of his persona and his hatred of masks. See the man who covered the wars as a reporter. The less than well off boy raised by a military step father and had a young wish to be Bucky Barnes until his "death" with captain America.
JJJjr is the normal man touched by the "Marvel" and the man is relatively unchanged from being a normal man willing to battle how he can with what he has.
