Love and still loved his X-Men issues. Lots of creativity, fun, and detail.
Everything else of his I have greatly disliked; it's like an eyesore to me much of the time.
Lee, to me, is the personification of a soulless corporate style. All flash an no substance. There is no loving hand behind his pencils; just a very fine-tuned and calculated style that has shown to sell for whatever reasons.
It's not that I don't think he's incapable of fine work. Every now and then I spy a strong cover or panel or two from him. But not too often because he doesn't really care. He, like his buddies Liefeld and McFarlane, are professional money-makers, not professional artists, IMO.
Look, they went into this business to make a boatload, and succeeded. One can't argue with that.
I know more of him than I actually know his work. At first, I had no opinion for this question, then, I thought, surely Lee has done some Spider-Man work. Nothing came to mind, so I googled and came up with Punisher War Journal #14,15 covers only. No wonder I don't know much about him! These covers are ok. They look good but are nothing special.
He also did the 1991 X-Men series, which I've gotten a few issues of over the years, though didn't buy when first published. I don't remember any of his work ever standing out to me, but, to be honest, I never paid close attention.
As for the Image guys making money, I agree, they were successful and there's nothing wrong with that but I can understand people who resent them, too. Sure, it was foolish to believe that the comics of the 90's were going to become as valuable as the comics of the 60's, but I think a lot of people bought with that notion. I'm kind of indifferent because they never got much of my money.
