This is my first post here, so if I may weigh in with my thoughts.
I'm 20 years old and in college, I love film of all kinds of film. Silents, hollywood classics, foreign movies going back to the 20s, even trash and underground movies. I want to experience the entire tapestry of film history. So I applaud the decision by TCM to air the friday night cult and underground movies, I think it can prove to be a real fun experience for movie fans. I don't think it would ruin TCM's reputation, I think it can act as a gateway for younger viewers to more classic movies which would be a very good thing. I watched a documentary on IFC this summer about the Z channel in LA in the 80s. They would air everything, classics, foreign and cult movies, had I been able to experience that it would have been a godsend. So if TCM became a little more like that, I wouldn't mind. I think a balance can be reached between classics and more programming geared towards younger viewers.
