PROS: I should start out by saying that nothing in this movie is really bad or really spectacular. The acting however is an exception to that statement. Every character was alert the whole time the film was rolling. Even though certain actors weren't speaking they were still present in the dialogue. This made it engaging, because every actor influenced the storyline. This quality brought the other aspects of the film up as well. The movie was scarier because of this, the films progression was better because of this, and the movies ending was better because of this. Everything just rolled together making this quite a provocative movie.CONS: The only thing that frustrated me was the description of the movie. I expected to watch this and have an amazing horror film, but this movie barely scraped by being an action drama. I understand there was guns, but that doesn't make it a horror, and the director and producer misunderstood that.www.chorror.com

Serenity House, a rundown London council tower block scheduled for redevelopment, is inhabited by a few remaining tenants who are unwilling to move out. When a teenager is beaten to death in the building, and no-one will come forward as a witness for fear of reprisal, a vengeful sniper armed with a high-powered rifle and laser sights blocks off all exits in the high-rise and proceeds to blow the heads off the tight-lipped residents.The killer in Tower Block is a truly incredible individual: not only can he take aim and shoot the dick off a gnat at 100 yards, in the dark, in under a second, but he's also adept at rigging complex booby traps in a public space without raising any suspicion, knows how to block cell phone signals and internet connections, and even has a designer's eye, rustling up a natty graffiti-style logo to announce his campaign of terror. That said, he's still no match for feisty blonde Becky (Sheridan Smith), who is able to thwart the shooter's best laid plans with a little help from her surviving neighbours, including local thug Kurtis (Jack O'Connell) and friendly, fearless fellow Neville (Ralph Brown).With a lot more care and attention in the script department, this might have been a taut little thriller—there's definitely the germ of a good idea in there somewhere— but too many far-fetched elements, massive plot holes and unlikeable characters (I struggle with wastrels, criminals and chavs as heroes—see also Attack The Block) prevent it from being a success, despite the best efforts of a game cast (Jack O'Connell's OTT performance is a blast) and competent direction from James Nunn and Ronnie Thompson. With lots of shootings and some reasonable action, it's never boring, I suppose, but it could have been so much better.Oh, and to the IMDb reviewer who described Sheridan Smith as 'a monster of a woman': get your eyes tested!!! She's a hottie!

This is a fantastic movie and even more so given it's a low budget indie entirely filmed in one small location! I have great admiration for a team that can put together something with the quality of this movie particularly with those obstacles. The direction is top notch, building suspense throughout, delivering unpredictable shocks & events and developing some lovely relationships between the people trapped in the building. The cinematography and music score are spot on lending a hand to the overall gritty industrial mood of the environment and sense of impending doom & hopelessness. But it's not at all a depressing movie. It's actually quite uplifting. I loved the characters and their believable and interesting interactions. There was some top notch acting from several people and the character of one in particular was so well acted & developed I wanted to see more of him!! Several other characters were also very likable and engaging while others were infuriating but you still didn't want them to get hurt. It's a fine movie indeed that makes you care so much for the people they've invented that you feel sad when the movie ends and they've gone. Yeah the plot had some holes here and there but they are not that significant in the context of how incredibly well this movie is put together. Most of the time it hung together well, people behaved as anyone would in the situation and it was mostly unpredictable. Special marks for having a strong female character, for not pulling punches about who "bites the bullet" and who doesn't and for the interesting side story of the alcoholic lad. And of course for the thoroughly fascinating stand-over guy. (I'll be looking for more movies with that young actor in them!!)The "reveal" and final scene could possibly have been handled better, but I've seen a lot worse and I was happy enough with it. In any case, the journey to get there was so engrossing and enjoyable it really didn't matter. The only truly (wholly) negative reviews I've read about this movie have focused on very trivial details (nit picking) &/or a couple of plot holes to proclaim this pretty much the worst movie in the history of the Universe. This seems a little petty & extreme to say the least. It's most certainly NOT the worst movie, nor is it the best but it's definitely one of the better ones, regardless of any flaws it may have. I say, you show me a movie totally without flaws and I'll find at least one anyway! :)I thoroughly enjoyed every moment and recommend it unreservedly for people who enjoy good drama, thriller, suspense, action movies etc and for those who like to see how a movie can be brilliant without the need for a huge budget and fancy effects.

OK, it wasn't great and it wasn't bad, it was what you make of it. Leave all your "buts" at the door and just accept the silliness of what's ahead. If you want a short, shoot em up, barracking for the Disadvantaged people movie, then maybe see this movie. I applauded film makers having a go, coming up with new story lines, new concepts, however we have had this concept of "escaping the unknown" plenty of times, but not so many times have we seen it in this environment, especially in U.K films.. Give it a go and like I said, leave your "buts" at the door.... because you never know what's lurking behind it..
