Drunken to Love You - I also had problems finishing the series as it began to drag after a while. One day I just watched the last remaining episodes in a go so I won't see it in my "watching" list. It was wasted time..
Full House and
Goong - can be kept in the list for days you have nothing better to do, I assure you that those series are acceptable. A bit boring at times but not bad.
Heartstrings - had a good start but it lost it's way after the first episodes. Dunno what to say about it, I'd drop it but you have only a few more eps until you finish it.
Love Contract - total waste of time. Poor acting and the plot goes nowhere.
Mary Stayed Out All Night - Cheesiness overload! If you're not a fan of either of the actors, don't bother!
Muscle Girl - The worst drama I've seen in a while. Even I have second thoughts about this one..And I don't drop series!
Prince Turns To Frog - Considering that Taiwanese dramas in general are awful, this one actually is a more down to earth, serious drama if you could believe me. I finished it a few years ago when my patience level wasn't so low and streaming was a pain in the ass. Was it worth it? I guess not, but at least it's better than 80% of the Taiwanese dramas that I've seen.
