The problem is Ghost Rider isn't bad enough to be up there with the Nicolas Cage "classics", and it's not good enough to be seen as a fun time at the movies. It kind of just exists in this rather bland netherrealm where mildly entertaining meets instantly forgettable. Eva Mendes is terrible and Sam Elliot is great, so the acting in this movie is all over the place.
Sure, I love any scene where Nicolas Cage starts freaking out as he changes into the Rider. Or the scene where he tries to scare him self by going "booga booga" in front of the mirror. It's especially great when the half rendered fire skull shows up (seriously, how did the studio approve this effect?). But they're few and far between. Better just watch the You Tube clips then.
