1.Crappy Crossovers-OWAW was terrible, and it went on for-fucking-ever.

2.Lateness-Planetary, Astro City, Tom Strong, Authority, all great books that will die or have already died because of lateness(though the reason behind the lateness is usually the main issue).

3.Bringing back dead guys all the time-Sure Green Arrow was popular, but it was because of Kevin Smith. It could've been the return of the Wonder Twins and if Kevin Smith was writing it it would've sold. Once he leaves what's going to happen to this book? It's going to suck. Speaking of sucking, Deadman and Spectre are the other two latest examples of once-deadman-now-walking, and both have bombed on the charts and probably don't have long.

4.Stretching franchises to ridiculous lengths-one of the main reasons why I don't buy Gotham Knights anymore: Because the arcs always end the same way, the villain is vanquished and everyone lives happily ever after. It never does anything, it might of well never happened in the first place. Completely pointless. The same goes for LotDK, and just about all the Batman mini series. The only Bat-books that ever do anything are Detective Comics and Batman. Similar patterns are found in big franchises like Superman, Xmen, and Spiderman. There are two books that really have an actual impact, the other monthlies and one shots and mini series rarely do anything, and the countless spin offs add up till you can't take it anymore.
