compared to IHYV, WYWS is terrible in terms of plot. sure, both dramas are very similar in terms plot and execution, but IHYV excels in both aspects much, much better. WYWS' plot is way too repetitive and bland and predictable; nothing new is brought to the table. in IHYV, I was on the edge of my seat and I actually felt the characters' emotions. I couldn't understand the characters in WYWS and they often did questionable things. cinematography-wise, WYWS is definitely better, but I don't watch dramas just to look at the beautiful scenery.
I gave IHYV an 8.5 and WYWS a 5.0 (dropped at ep 16 and browsed the finale. felt like I didn't miss a thing)
