Early 2000s korean dramas and movies

I feel like a lot of these dramas would have poor ratings (too much misunderstandings, lack of communication, grooming, jerk ML, weird music and effects, clichés...) if they were airing now, but we still enjoy them because of the nostalgia and of the fact that they don't make dramas and movies like these anymore.

My rating system :

• 10/10 - A masterpiece.
• 9/10 - An outstanding drama, but still not a masterpiece.
• 8/10 - Fantastic overall, though it may have a couple of minor issues.
• 7/10 - A good drama that, while not groundbreaking and with its share of flaws, still manages to entertain me.
• 6/10 - An okay drama with its strengths and weaknesses, but the positives outweigh the negatives.
• 5/10 - A mediocre drama where every positive aspect seems to be counterbalanced by a negative one.
• 4/10 - The negatives outweigh the positives.
• 3/10 - A poor drama that may have a few redeeming qualities but overall offers a disappointing experience.
• 2/10 - A terrible drama with perhaps one redeeming feature amid a slew of shortcomings.
• 1/10 - An abysmal drama that feels like it shouldn't even exist, ranking among my least favorite dramas of all time.
