may be it's because I had really some big expectations for this series but after completing it I can properly say this was just a waste of precious money, hardwork and time. This drama had everything a hit series needs to have but they couldn't develop:

- the love story "the main theme of the drama"
- the time slip cuts
- parallel dimensions should have to be mentioned a lot before "not just in the last 3 eps" it simply confused viewers
- it does had to have at least 20 eps to finish it without any hole to fill
- really rushed

To be honest I lost my interest in ep 8 but I kept watching it only for Lee Min Ho he was such pleasure for eyes so I thought to finish it just to see him and it was a great decisione. Well I can't say I hated the drama, it was passeble but they could do a better job
