Phantom: Requiem for the Phantom is an absolute must see!
If you're like me and like more defined graphics and a plot with suspenseful and intense twists then this is the show for you.
The opening is a bit quirky but the love story behind it all is...as it is through the series.... transformative.
The series also takes hints from western pop culture. Ideas that I dare not risk spoiling might come off as a bit comical.
Though I give this anime a great rating, I would say be prepared to be on an emotional roller-coaster. especially so to the weak-hearted like myself.
All in all i would say that this series is definitely worth the watch if you have the time.
