I get what Marvel is trying to do, but the X-films have been very successful, despite not having much in the way of movie tie-ins from merchandise or comics ever since X1. The fact is, comics don't drive movie success. I don't see Marvel's actions having a major effect on Fox's success with the X-Men, and instead, this is more significantly going to cost Marvel readership and profits from what has, since the mid-70s or so, been their most popular team. The Inhumans ain't the X-Men, and comic readers aren't going to be swayed to think that they are. But it is what it is. Having grown up reading and loving the X-Men more than any other comic, I think this is a bummer. But it won't last forever. Either Marvel's Hail Mary attempt at getting these rights back will succeed, or they'll eventually realize that that it isn't working and will usher the X-Men back into the fold.
