It's over ten years since Gene Siskel died.
Here is a cool clip of him and Roger Ebert bickering:
If Ebert was better at wordsmithing, Siskel certainly was better at understanding the art of film, and things like character development. However, he was not a great critic, either, and also seemed to fall along the like/dislike emotional axis rather than the good/bad intellectual one.
Still, 10+ years. And now Ebert seems ready to kick off.
