One huge plus for Siren: Blood Curse is that it does take advantage of its episodic nature, despite not really being released episodically. Think of Siren not so much as a brand new series, but as something you pick up later on DVD because your friend told you it was worth checking out. With each episode comes a different playable character and thus a different twist on the mechanics, meaning that even if you didn't like the episode you just played you're bound to get something different on the next. It also features a dramatic intro sequence with every episode and ends on the note of, "next time, on Siren." It's enough to make you growl, "previously, on Battlestar Galactica" at the beginning of every new episode before you curl back inside yourself.
Bottom Line: Appropriately enough, Blood Curse is the Siren of 2008 as it's an awkward and ultimately shoddy production that is just unique enough to gain a cult following despite its laundry list of faults and short comings.
Recommendation: Only serious horror junkies looking for a fix need only apply. You'd better have some Silent Hill audio dramas signed by Yamaoka himself.
