Aint gonna lie .... i totally HATED how it end ( escaping reality by COMMITING SUICiDE?) .... much less explain what was really going on in the first place..... is it the mind ? is it reality ? which is it ...... if its time travel stick to it .... don't mess with audience about ifs and what nots....

I would have given this a 10 if REALITICALLY speaking .... common sense would tell you THAT it SHOULD end the way its should. i mean what was he at the end ? fact or fiction ? was it even explained ????

dont get me started about THAT phone call!!!!!! oh and only in Kdrama land where you can have brain surgery and STILL have a full set of hair post surgery .... HILARIOUS !! =) gotta love Kdramas!!!!
