Messy handwriting is not necessarily indicative of “bad writing,” just as neat and nice-looking handwriting is not necessarily “good writing.” Handwriting style is highly subjective and can vary greatly from person to person. What matters most in writing is clarity and legibility. If the handwriting is clear and can be easily understood, it serves its purpose effectively, whether it is neat or messy in appearance. Neatness and aesthetics are personal preferences and do not necessarily reflect the quality of the content being written.
