It does seem a little disappointing at first glance, I'll agree. But the result of the 'did you go to church last night' poll right now stands at about 65% 'no', so there's still hope for us yet.
I wonder how many of the rational folks among us still went to church anyway because of family tradition/pressure. Poor guys.
As a nonbeliever who has been to a few masses, I can tell you it's not lethal. It might be a tad boring - but there are much more boring things you can be forced to do on special occasions.
