Whew. So maybe it was that you watched Persona, and couldn't enjoy the next two films, and after Scorsese the same happened again. 
I also have problems concentrating on the next film, if I see a great one before that. My mind keeps wondering back to it. Just saw Vincent Gallo's The Brown Bunny (2003) again during the weekend, and I'm still thinking of it. In comparison, I didn't enjoy the last three films I watched since (by Kitano and Tati!) very much. Great films exist kind of in a world of their own.
