It was a thrill,a psychological mystery that i personally love as i am a big fan of movies that make you think! There's a famous saying in Greek, it goes,"If you want someone to hate you,make them think!"..So some people might not like this movie as it does make people think.. So the Plot is terrific,acting was pretty decent.Cant say that anyone "Over"acted or something..Direction was pretty simple as the whole movie is made in one tiny little room. All in all,Good one..Liked it a lot..Recommended for people who like to think while they watch a movie,this isn't a movie for you if you just wanna pass time and wanna "Hang out"..Cheers..
