This movie is a lot better than what passes itself off as either a thriller or a sci-fi, these days. Definitely worth a watch. Admittedly there are a few plot holes and some bad acting. But they fade away in the background, with the edge of the seat suspense and drama the director manages to portray throughout the film. The editing, albeit, is rather disappointing. I don't know if it's just with the version I watched on YouTube or if it's in the original as well. It doesn't affect the storyline as such. Some scenes are just jumpy and appear to come out of nowhere and one thinks one has to put them in context. But again the director comes to the rescue and the pieces coalesce themselves naturally.
An underrated film. Deserves better reviews.
