Heh, I think expectations are probably different/have changed for those of us who don't have a choice. These days, my expectations are fairly basic: he's actually a true priest and he's Catholic.
But having run CathInfo for 12 years, I'm quite familiar with how critical actual, flesh-and-blood Catholics are about their priests. Sometimes the criticisms are mutually contradictory: in many cases, the priest is "damned if he does, damned if he doesn't". People will always find some thing -- large or small -- to criticize.
That's why we need to be more forgiving and understanding about our priests. They're only human beings. Unless they are committing serious evils (scandals, slandering other priests, causing unnecessary division and hatred among Catholics, etc.), we should cut them some slack. And in any case (even if they are evil) we should certainly pray for them.
And at all times, we should be willing to "give the devil his due" when it comes to priests. If a priest does a moderately bad thing, for example he refuses to submit himself to any faithful Traditional Bishop anywhere in the world, he still might have many good qualities. Perhaps he is still well-trained as a Traditional priest, with an impeccably valid ordination, faithful to the Traditional cause, and he might be doing a lot of good with the Faithful; he's just a bit headstrong and lacks the virtue of obedience. In other words, we should keep things in perspective.
People love to turn everything into black and white, a bunch of spotless saints on one side, and a bunch of incarnate devils on the other side. The real world is much more complicated than that.
Nowadays, if a priest doesn't perfectly agree with all of one's opinions important or otherwise -- or if he fails to align himself with your favorite group -- he's flawed merchandise if not an outright villain.
