The Grudge (2004)
I have friends that have gone to Japan and loved it. I feel like I would go to Japan and be greeted by string-y haired ladies at the airport trying eat my skull. Granted, Sarah Michelle Geller (I know her character has a name, but let's face it - she's playing SMG) is sensible and realizes she has to work while abroad and takes care of old people. While we all need money to live, if I had to work in this house I would have turned around and gone home.
The Grudge is an interesting take on the whole foreigners in a different land genre. These are not random university students who want to dick around and get drunk. They're adults. Who have jobs... and affairs. But, um, anyway... It is a fascinating and unrelenting look at a very deadly culture clash.
Texas Chainsaw Massacre (1974)
I love my friends. So much so that we never leave each others sight. The amount of thing that could have been solved in TCM by the not-so-bright group of teenagers if they had simply stayed together is probably the most terrifying thing about this movie.
An American Werewolf in London (1981)
AAWL is a curious look at back-packing. Again, not the Hostel version of back-packing but two old friends looking for a good time. After one is horrifically killed after they wander into the Moors the other carries on, this time with a curse. Again, we're looking a the trope of the "wise-locals". The locals who should say or do more but only give our heroes cryptic, ominous messages.
