LEM, it depends on your definition of a "good" landing.What the passengers (and cabin crew) consider "good" is actually a SOFT landing.The fact that it was halfway down the runway,off speed,off centerline,wrong rudder,innapropriate for the rain,just lucky etc etc etc never enters their heads.
A "good" landing is on the TDZ, on speed ,on centerline,aligned and without bending the aircraft.The outcome on the day for many types when all the above is either firm or a greaser.Thats often a question of luck,or the slightest of differences.Both will be "good" landings.
You have probably never encountered a true "hard" landing which requires a check.I've absolutely stuffed the Boeing in a few times (I'm Captain BTW!)and it was never anywhere near the limit.If it is truly heading for a "piano landing" I'll jump in but I'd never ruin a good clonker! Nobody ever ruined mine.
ps,as a pilot you are only as good as your last landing-ask the Hosties!
