The signal is a very exciting science fiction thriller, although how many thriller begins first quite harmless but powerful turning up with time and there is gradually an overall picture. It has at the end (which is indeed very surprising for me came and surprised me even in nature) in theory, the possibility left open in order to turn sequels can. The scenes in the abandoned house are already turned very oppressive and have something of horror movies even if the focus of the film on other areas is as - where am I? what is happening here? Where are my friends? ... Would that be here just for Facebook I "thumbs up" say ;-).
