Siskel liked highbrow shyt, Ebert liked lower brow shyt - his main criteria if o remember was did a movie succeed in doing what it set out to do, regardless of budget.
They had a hardcore rivalry in Chiraq, while working for different papers, if I remember, so seeing them together on the old local show was cool. If they agreed on a movie, it was dope.
I do love Ebert's philosophy that a movie is about more than what it's about. I try to tell my friends that all the time. Just because you love the subject matter of something like Dear White People doesn't mean that alone makes it a dope movie. How it accomplishes that and executes it is just as important if not more so
