This drama had a lot of potential, given the plot and the cast. However, it never delivered. For one thing, it never made sense, and just when you thought it might, that everything will fit and come together, it cheaps out and just makes even less sense. There are gaping plot holes and I'm left wondering if it's actually the drama or if that's truly how the book upon which it is adapted from was written. One glaring flaw, for example, is that the whole explanation of how the time travel happens is never explained nor addressed. I have never seen a drama or movie, nor read a book, in which time travel was the theme, that there was never some sort of explanation, no matter how lame. Given that this was the basis of the whole drama, shouldn't some sort of explanation been given? Acting wise...I was extremely disappointed with Gackt's performance. This man is one of my favorite actors and I think he is highly talented, but in this drama, he seemed like he was merely there and trying hard to stay awake. It was kind of shocking how lifeless and dull his acting was here. Also, and this is minor but annoyed the crap out of me. Never once did his character change clothes. I mean, what? Did he never take a few moments out from time hopping to change his outfit? It never had any wrinkles or stains. Would it have killed the production budget to give the man a couple of outfits to change into like everyone else? The other actors wers ok. Nothing too special here. At least they had adequate changes of clothing, though. Overall, this drama is watchable, but barely. It could have been so much better had more thought been put into delivering it and more sense made in the plot. Would I reccommend it? Not really. Especially for Gackt fans, don't watch it. It will be a huge disappointment for you.
