Well, until you realize how unbelievable the entire genre is. Then it's just aggravating. Old man yelling at book "don't you realize your tropes are completely stale??"
Sure, that's a state that will persist until it doesn't.
One common barrier to suspension of disbelief is the Fermi Problem. A great deal of space opera just ignores it, but once you take the argument seriously it ruins much of the world building.
If I want to ignore rationality of the world design and just read human achievement porn I'll head over to r/HFY.
I thought that you were going to condemn the genre's ubiquitous faster-than-light communications/travel. I approach space opera as a specialized variant of high fantasy, where the usual tropes are as genre-acceptable as wizards and ghosts.
