Three Stars

Mostly harmless, with some good acting.  But  Yang Dong Geun as the lead man seemed flat and uninteresting. He just didn't bring any sparkle or life to the role.   This could have been great with Jang Hyuk, Ji Sung or Lee Min Ki in the lead. Park Han Byul was delightful as the robot mom, and the supporting cast was excellent.  Ivy's final scene was a tour de force.  A so-so drama as it was, the  very good writing and direction would have been better served with a livelier lead man.
