A cabin manager viewpoint here....... no he shouldn't. As crew we occasionally take the mick out of landings but we are taking the mick out of our own.
One of my bug bares is how passengers 'gush' over the pilots (often ignoring the hard working cabin crew who have catered to their every whim for the last X amount of hours) saying how good the landing was etc. At the end of the day, Joe Bloggs doesn't really know what a good/skilled landing is. The same goes for a 'bad landing'. They may not know the circumstances surrounding that landing.... blah blah blah.
