One thing that always bugs me is that all Asians are required by Hollywood Law to always have an accent, even if they speak perfect English.
And if there is an Asian actor who is half-Caucasian, they will be given the larger roles while "pure" Asians are relegated to thugs and lesser roles, a la the Chris Farley classic Beverly Hills Ninja.
But back to topic, I saw Hostel, and man, it was brutal. It wasn't the gore, it wasn't the atmosphere, it was the poor guy's screams as he sat strapped in the chair being tortured. Very convincing job, even made ol' TJ cringe a bit. I can easily stomach those surgery shows and I always know I'm watching a movie, so I can usually take this stuff (though the tongue cutting scene in Ichi the Killer was a bit hard to take).
Overall, not a bad production, though not really scary, not really original, and not really effective as a horror flick. They just try to gross you out instead of getting inside your head, which is where the best horror movies go. Definitely not for the squeamish or faint of heart, nor those who prefer their horror movies to be more cerebral and less visceral.
