I have noticed a pattern with romance manhwa that get to be animated or get a drama. They receive a boost in ratings from new fans, and then are subsequently critiqued more in depth by readers once they have been completed. For example, True Beauty received astronomical ratings when it was first up for reading, but after the drama came out, there was a wave of more in-depth reviews, discussing the repetitive cycles found in the webtoon. The initial high rating score for the manhwa reflected how addictive and good it was for a “binge-read”, whereas the later critical reviews found the same and added more depth to the praises.
'What's Wrong with Secretary Kim' also has a high rating and it also attracts millions of new readers through the live-action drama. However, these days, the webtoon itself is rated by many, including webtoon purists and drama fans, in the review section. So, be careful because the high rating of the manhwa may come from the cross-media boom and always check the date of the reviews to see whether they were written before or after the drama was released.
Just thought I'd add my 2 cents to all of these great suggestions. My bookmarks are a hot mess of randomly added sites that I have no idea how to search for by name.
“The Ember Knight” is a niche book that looks really simple at first but is actually very smart. The characters are all unique even with their helmets on, it’s a very strategic and well actioned book, and the use of shadow and silhouette is brilliant for mystery and tension. A book of complex plot to be served by smart art. Rather than big, splashy, energy based pages, you get cleverly composed pages that encourage rereading and thought. Very clever and therefore worthy of commendation.
Unorganized as it is, this is how I do things. My bookmark page has over 15 different manhwa sites all neatly organized in folders. When searching for a specific series I normally open 3-4 of the sites in different tabs and compare the following: image quality, ad size (with ad blocker enabled of course), and how user friendly the site is to read. It adds about a minute to finding a series but 9 times out of 10 I’ll find a better version of the manhwa than what I would have found by clicking the first result in a Google search. I do this because it is basically digital window shopping for the best way to read a series. The “best” site to read a series can change from series to series, and even within a series from chapter to chapter, depending on how up to date the best mirror is.
