I liked Bride of the Water God for a while...And then the plot just didn't keep with me... As for Red Soul, I started to read it, got past the first five chapters, and then dropped it. (I swear I remember manga/manhwa/manhua by the cover art seeing how I'm literally googling each series up to see whether I read it or not)
I read Video Girl Ai during that time period a few years back (4? 5?) when I was obsessed with Tragedy and Angst. I dropped it when it was somewhere really close to the ending. It was just.... I just felt nothing for it after reading and watching Saikano.
Saikano was the most depressing piece of work in the history of everything that I've read. Haven't felt sad for any manga/anime/manhwa/manhua ever since that series. (No, not even CLANNAD, AIR, KANON. Then again, they were not my cup of tea. I felt nothing at all.)
And again, I haven't liked anything with the main theme as romance for the past three years... Other than those comedies that's literally the "laugh-until-your-stomach-explodes-and-you-drop-dead" kind. Even though it's a one time thing...
