This movie is the proof that the world is becoming a sick and dumb place

Great Film overall

By the time the dramatic fireworks start popping off, each one feels earned.

It's every kind of crap you can imagine, unless you live in the UK and have a terrible phobia of chavs this movie does nothing for you.It's storyline is pointless, boring and makes absolutely no sense. The characters drain the life out of you, the killer teens could have made it interesting but no they kept them just like the rest of the movie; a pile a crap (I feel like I'm using the word crap much but it really is a load of crap). It's abrupt ending can only be welcomed with open arms and a bewildered feeling left in your soul that the only scary thing this movie did was eat 79mins of your life and that you'll never know why any of that happened.So to sum up everything; this movie only has the stars it does because of hipsters liking things other people don't. It tried to be edgy and dark but was just a uninteresting,terribly written, bland, poorly shot,non scary pile of crap and I feel so bad for people who paid to see it.

I know that there is no golden rule saying that all characters in a scary film must be likable, but I think that it really helps one's overall enjoyment of a horror if there are at least a few people to identify with or root for; similarly, there's nothing to say that indiscriminate on-screen carnage needs to be justified, but it's quite nice to be given a motive for such behaviour.F, from director Johannes Roberts, features almost no-one worth caring about and offers little explanation for its random killings, making it a very frustrating watch—a shame, because the basic set up has plenty of potential and Roberts shows a lot of promise with his handling of the visuals, making great use of his surprisingly creepy setting, a secondary school after hours.Things go wrong almost immediately with the introduction of the film's central character, teacher Robert Anderson (David Schofield), who loses the viewer's sympathy with his insensitive and very unprofessional classroom manner, belittling his less able students in front of the whole class (and quite deservedly getting a head-butt for his troubles). We then get to meet Anderson's bitchy superior Sarah (Ruth Gemmell), his wayward daughter Kate (Eliza Bennett) and her douche of a boyfriend Jake (Max Fowler), and the world's most useless security guard, James (Finlay Robertson). So many horrible people in one building...The killers in this film—faceless 'hoodies' who understandably have issues with Anderson, but who for some reason also vent their rage on less deserving members of staff and their own peers—prowl the corridors of the school like wild animals, quite literally at times, silently scaling furniture and shelving to pounce on their quarry; I understand that Roberts wanted his killers to appear predatory, but he takes it just a bit too far—I've seen ninjas less stealthy than these kids. It's all a bit hard to take seriously at times.The dark locale does allow for quite a bit of tension, the odd shock, and some occasional gore, with the death of F's only really amiable character, hot teacher Nicky (Roxanne McKee), being particularly nasty, but as a whole it is a very flawed film, the inconclusive and unsatisfying ending being the final straw.

This film looked quite good when i first learned about it but as soon as i watched it i thought that was the most wasted 1 and a half hours of my life. I thought the plot was dreadful and how many schools have security guards anyway? I know for a fact i am not the only person who thought it was crap as i leaned it to my friend the next day and he said exactly the same as me. I am glad i only paid £1 for this rubbish as i would be mad if i would of paid more for such a rubbish film. Usually i enjoy films as i own over 350 but this was dreadful. I did not only feel disappointed by this film but i also felt quite uneasy about this film as people are murdering school teachers for no other reason than for fun. Even a poor security guard is locked in a bin and set on fire and i felt who would do that. I know it is only a film but i found it disturbing. This film is one of Britain's worst films ever made. Anyone who is planning on watching this film should have second thoughts about this film.

F is one the best pulp horror movies I have seen in these last years. In the same class of the french "Ils" ("Them") but less handicamish.I am a passionate fan of horror movies. With movies like these you either feel afraid (that deep discomfort sensation that awakens your senses) or not. If not, they they miss the point. F delivers just that. It is really scary in the "it could happen to us" category.The hood gang is a great portrait of pure evil (such as Halloween's Michael Myers), but this time evil walks in a pack and you never see its face. The director never shows or tries to explain the reasons behind the hood gang killing spree. You just see them happen and they make sense. The actors are superb, especially father and daughter.Hope the director makes a sequel (although I know it wouldn't be as good, still...).
