RottenTomatoes.com has Bloodrayne at a whopping 5% fresh. Ouch. Still, not as bad as Uwe Boll's Alone in the Dark - which stanRAB at a record-breaking 1% fresh. Which I understand is the lowest ever. Quite the feat.
That's a lot of reviewers for Uwe Boll to thump, there (43 for Bloodrayne, and 109 out of 110 slating AITD)
