I can understand passengers feeling a bit apprehensive throughout a turbulent approach. Concentrates the mind a little for the pilot too but we've all done it many times and the option to go around if things become too severe is always open.
Where you are seated can make a difference to your perception. Sitting right at the rear you are out on the end of a long arm (the fuselage) and any pitching and/or yawing will feel accentuated.
People pay good money for that kind of experience at the fairground but I'd suggest our standard of maintenance is a wee bit better
