I liked this movie. I'm not sure why they called it Cello, because it's the characters in the movie that really make it scary and not the instrument. But, it is directed by Lee Woo-Chul, a music director, and he really does use the music effectively to create this creepy ominous vibe. He also makes the movie look good too (there's a lot of cool imagery) and it comes off almost looking somewhat like a longer version of a scary music video. Maybe that's what they decided to name it after an instrument. Anyway, it's about this woman, who is a really great cellist, and she just wants a peaceful life after surviving a car crash that killed her best friend. So she decides to give up a professional career in music in favor of teaching college students and her daughter how to play. Well, once her life appears to regain a sense of normalcy, of course you know that that's just the quiet before the storm. Suddenly, one of her students attacks her, her sister in-law develops a wacky obsession with her fiancée, and the new housekeeper lets' just say the woman will scare the crap out of you! Plus, her daughter develops some serious issues, including a nasty biting habit. There are plenty of scary women in this movie and they had me jumping several times. That's why I reiterate it's the characters that you have to watch out for. Before I saw it I thought it was about this haunted instrument or something. The acting is good, and the music really does add to the jump factor. Basically, it's a really fun movie to watch late at night
with the sound up loud. I recommend it!
