It's probably different to different people, but I'm having trouble with old movies for a similar reason - they feel too slow to me. The plot doesn't develop fast enough; sometimes I actually can't make heads or tails of it, because some events are spaced out in a way that breaks the casual relationship in my mind.

The what it differs from what you described is that I don't mind active, decision-rich entertainment. I love video games. I just have too short of an attention span to really enjoy old, slow-paced movies :/.
