On the topic of not developing villains these days I couldn't agree more, I was mentioning this a bit back in a previous aimless rant I did. I think it probably comes down to a mix of things.
Firstly I don't think many writers are given the time these days to develop new villains across multiple issues and actually make them seem formidable, between short series runs, event tie ins, guest appearances to appeal the book to new readers and rebirths/renumbering how many consecutive issues do most writers actually get.
Then there's the modern trend especially in Marvel where a lot of the time the main villains to characters are actually other heroes they have different views on or team members they have infighting with, villains are just added as background noise/throw away appearances.
Its a shame because I think that can add to fatigue of reading the big two Marvel/DC especially seeing the same villains show up again and again with only slight differences and your meant to be shocked and amazed.
I also want to hug the sad ghost/god
though would that be possible due to ghostyness or smiting. Though maybe hes somewhat corporeal if hes wearing his little hat there.
