Monster Fail: When Characters "Grow Up" Badly

I guess this is going to be the closest I get to reviewing Monster, because I couldn't take it and dropped it, which is rare for me because I am a finisher.  But unlike all the other stupid shows that I finished when I should have just dropped them (like My Barfable Girl and Boorim School) I knew when to quit with this one.

Escape! There are 30 more episodes!!

Maybe because it is 50 episodes long and I couldn't even force myself to watch episode 20... That might seem like too long already, but I did want to give a chance, because Park Ki Woong, but it wasn't enough.  One of the biggest reasons I couldn't muscle through was that I couldn't like the main couple.  Well, I honestly didn't like the main dude.  He just wasn't right for that role, and the biggest reason was because he was too old and nothing like his younger self.  For the first time, the younger selves were better and everything was ruined when the show time jumped our OTP (and I use that term loosely) into a pair of less likable peeps.
