Underworld

Beneath the surface, in the shadows, a dark sphere; two hostile factions, scythe and rip, and claw and shear; a battle born of ages, a perpetual war rages, without forgiveness, without compassion, just hate sincere.

A warring vampire makes a link to treachery, this wolf assassin's stalked Lycans for centuries, hidden secrets are revealed, open wounds that never healed, genes are diced and spliced to halt adversaries.

It's only downhill from now on, as the franchise ruptures, the bloods gone, not quite knowing when to stop, perpetually draining a good plot, leaving a husk, a shallow spectre of what was.
