Personally I had trouble staying awake through The Amazing Spider-Man, but that wasn't any fault of the cameras used, it was just another why-did-they-bother movie.
This is far from the first film, video, back-to-film, video, back-to-film etc cycle I've seen but it may be the last.
Ironically after all the Hoo-Ha about the "revolutionary" Genesis being used for Superman Returns 8 years ago, Superman The Man of Steel was also shot on film, plus the Batman films of course....
