I know I stopped reading and collecting Spawn for two reasons. The first was that this was always an art driven title, and not so much a plot driven one. I never knew or truly cared for any of the characters. And the second reason, which sadly is still true for all Image titles today even it being 18 years later, and that is constantly coming out late.
Way back in the ancient days of comic book reading, us old timers would actually take the time and physically write letters to Marvel about a mistake in continuity in that certain book. I think that it would be fun if we comicviners would list all the mistakes that we see here on this page.
