Unless you speak Thai (or have really good subtitles) you're going to miss half the jokes e.g. they're mispronouncing "Madam" as "black dog", and "Jim" can mean vagina so the Caucasian lady is saying "now I have two vaginae: a big vagina and a black vagina". Funny, ain't it? The other reason to see this movie is to see Pornchita, a famous Thai model you've never heard of (her nickname is "Benz" like the car) playing the role of a country bumpkin. Still, it's better and more coherent than most Thai comedies, and better than that J-Lo vehicle you were reaching for when you accidentally picked this one up at the video store. But do yourself a favor: next time stick to the ghost movies. (Feel free to verify "vaginae" in your dictionary.)
