The most disturbing film I've seen is probably August Underground Mordum. Really pissed me off that movie did coz I loved it and I shouldn't have as it's a sick puppy.
Didn't find it offensive though.
Not much offends me except crap Irish(Oirish) accents in movies...we don't all sound like leprecauns here. Oh be gorrah, be de hokey, where's me pot o gold. If your gonna play someone who's Irish listen to some Irish people and don't just 'study' by watching Darby O Gill a few times.
