No, it's directly relevant to what the thread's about since so much dialogue-heavy content these days is poorly written - and I therefore can't blame modern cinema-goers getting bored with it much of the time. It's a pertinent point and perfectly appropriate to the subject of the thread.
Way to miss the point. There are people who can't tell the difference between good dialogue and terrible dialogue; they consider all dialogue boring - regardless of the quality. That is what the OP is talking about. You opinion is perfectly valid, just not what the thread is about.
