Cherché sur le net justement pour connaître le ton du film :
Eubank gets some serious mileage out of what has to be a minimal special effects budget. Doled out sparingly, the CGI manages to make an impact when the movie needs it most. But there’s also a surprisingly moving human element to The Signal, and Eubank skillfully manipulates the tone to achieve the best possible result. Yes, he also cribs liberally from other, better sci-fi movies. But it’s obvious that Eubank is trying to create something different here, something memorable. While The Signal may not be perfect, it’s not a movie you’ll forget anytime soon.
bloody-disgustingDirector William Eubank keeps things tense but believable – just unusual enough to compel you, but with the details kept in the background of what becomes a quest for answers and freedom. Fishburne seems to toggle between reassurance and menace, with his quiet but firm performance.
Thwaites and Olivia Cooke (as Nick’s girlfriend) help you buy into the story; like the viewer, these characters can’t quite believe what’s happening to them. With a minimum of special effects – but a couple of wowsers – it pulls you in and doesn’t let you go until its unexpected ending.
