If you haven't bought the DVD and watched it yet, I pity you.
I can only describe it as... Do you remember the time before BSG, then BSG came along and you found this incredible new show? Razor is sort of like the new great moment where things kick up a good notch and redefines television viewing.
Like I said in my review (or rather, pointless rambling), I gave it a twenty out of ten. A completely flawless winner.
