cursed is a pretty straight forward movie really although with bad translations and a washy plot it can be difficult to follow.
the beginning sequence is actually the end...which is usually a pet peeve of mine but i'll give it the shock value it has.
the plot: difficult to say what the plot is beyond a store that is cursed because the builder used crushed tombstones to make concrete (sure!). the owners are creepy sometimes and totally off their rockers other time, and yet comatose other times. they refuse to sell to a bigger corporation that wants to buy it and the woman who is sent there to try to convince them to sell (a second time) for some reason begins taking inventory in the shop. the two workers, on day and night shift, a girl and a boy are falling in love. much of everyone who comes into the store gets cursed and is killed or, as we learn about the original man who offered to buy the store, commits suicide. the only two people in the store that survive both see the odd things about them and in the store as well.
what ever you make of the movie, parts are like a tv soap opera and some are more cinematic. nothing really surprises, scares, is particularly gross, or that dramatic. its a bit middle of the road really. nothing great, an interesting cast and cursed store, but not phenomenal by any means.
