Below the summaries of each drama, there is a list of reviews posted by the reviewers. This list should be listed with the latest reviews first. Currently the first reviewer dominates and often gets the most 'found it useful' since most of us would only read the first few reviews. Let the later comers have a chance to be seen and heard.
The first may not be the best review and could carry with it bias. Someone out to sabotage a new release could jump in to write a negative review with intend to damage the viewership and rating.
I can give an example at https://mydramalist.com/34637-the-legend-of-xiao-chuo. The first writer gave it a 4 when eventually, it reached a 7.6. I gave it a 10 as I think this drama is really good. I think the first writer had bias the rating.
