I'm thinking of subscribing to Marvel Unlimited, but I've heard that there are big gaps for stuff before 2000. As I'm really interested in getting into 90s X-Men, horror titles (Ghost Rider, Nightstalkers and other Midnight Sons titles), late 80s/90s Spider-Man and Venom, Daredevil, Punisher, this could be problematic for me. I did read somewhere that the library is updated weekly; overall, how complete is it, and is it worth it for my wants?
