Watched Ghost Rider: Spirit of Vengeance and as mentioned by previous posters, it was decent. However, it was not better than the original, in my opinion. They also changed things like who and how the curse was bestowed upon Johnny (by Mephistopheles in the first film and Roarke? in the second, paper cut in the first...). I also hated the new bike he rode on. Where the hell was Grace? No Penance Gaze, etc.
Also, the 3D was barely noticable, as it was converted to rather than filmed in 3D.
