Denofgeek.com knows them all.

Red Sonja? Nobody wants to see that. Tintin? Stupid idea. Only works in the original medium. Witchblade? Again?

Submariner? You gotta be fword kidding? There's an old rule in the comic industry: Aquaman doesn't work! No, "caught up in an ecological war" doesn't work either. And the Submariner is just like Aquaman (except for he fought in WWII and he has cute little wings on his feet).

I wanna see the Jonah Hex movie though...
