2) Monthly Books that are not monthly
3) Continuity Issues
4) Too Many Crossovers. WAY too many!!!!
5) Stopping and Starting of Comic Book Series
6) Too Many individual writers working on multiple books (Geoff Johns, Mark Millar, and Brian Michael Bendis are prime suspects of this)
7) Cover artwork and Interior Artwork need to be the same person.
8) No "House Style" Artwork
9) Books never ends (I know this goes against #4 but there can be an acceptable middle.)
10) No real Artist & Writer teams any more. (Wolfman & Perez, Claremont & Byrne, Kirby & Lee)
