I think this is the situation that helped develop the critical confirmation rule in the first place.
Perhaps you could add a rule that requires you to be able to at least hit the monsters AC with a 16 or better. Unfortunately, that means you can't critical a monster with a very high AC at all, which doesn't seem like much fun.
Or you just decide it's not a problem. If you can only hit on a 20, only supremely lucky hits are going to do any damage. It's the "Smaug" or "Achilles" rule.
If I can only hit my opponent with a Natural 20, then I'm only going to do damage if I find the only chink in his defense. And if I'm that lucky, the hit should be a crit.
It doesn't bother me, especially using Fourth Edition's "Critical hits maximize damage" rule.
