Don't bother.
At one point I was going to suggest watching the first 20 episodes then skipping to about 70 and picking up from there. But the series fell apart in the last few weeks and it's not worth bothering.

I can't believe that a writing team that HAS done a 120 ep daily before did not plan out the plot better. They could have easily fit in all the plot lines they wanted to, but instead wasted 50+ episodes with nothing happening and then tried to cram everything in at the last 3 weeks. CRAZY!!! They left plot-holes galore, undeveloped characters, no chemistry, ridiculous premises, unpunished villains, and the list goes on.

The could have saved it (Kinda) if they had the guts to make the ending sad or even bittersweet. It would at least have given the series a point. But instead they pulled a monkey out of a hat (not the metaphor I wanted to use) and came up with A HAPPY ENDING. Good Grief.

All this in addition to the worst ML character I've ever seen. I feel sorry for the actor playing this loser and I hope that he does not get typecast in the future.

The only redeeming thing in this mess was the acting of the daughter by Kim SiEun. Her growth as an actress thru this was amazing and if she doesn't get Young Actress of the year at the KBS Awards in December, it will be a crime. She could easily compete for Best Actress, period. As much as I disliked her character, it was her performance that stole the show.

So again, don't bother watching this. It's not worth it. And a curse on the writers and producers for wasting an interesting concept with undisciplined writing and poor oversight. And toss the Director in the Fiery Pit as well...
