Dont get it!!!!

Not everything needs to be spoonfed to the viewer. Every single aspect of a story doesn't need to be displayed in gory detail. As for how they were moving, google "parkour".

"Nothing says "OBEY ME" like a severed head on a fence post."

Same, they was more than 1 hoodie though.
I didn't get the motivation either... I grasped the fact that they were "F" students but that doesn't even remotely give motivation for running around their school at night, smashing faces, defacing and generally torturing the hell out of teachers...
I also don't think enough was given to work out a motivation, maybe the writer didn't even know and I certainly don't expect the movie to "spoonfeed" us, but at least give us a little pointer into the right direction....
Despite the bad writing (I would put it down to that) it has some decent effects in and the acting wasn't too bad...
Agree with you on the ending as well... There were just too many things left unanswered... Maybe it's just me though...

The strange noises that surrounded them, the way they moved and the fact they never spoke and appeared to have no faces suggests they were supernatural.

It wasn't that late. If school finishes at 3.30pm and Katie had an hour's detention then it kicked off no later than 4.30. Probably a bit dark for that time of day even in winter, but it happens.

Hey there.

Sorry but -and I mean it in the nicest possible way- why don't you use your imagination? A film doesn't have to be "explained" to you: it's not a financial article. Think about what you just saw, and try to understand/guess... Any work of art is a collaboration between the artist(s) and the audience. Both have to play their part in the process.

As far as I am concerned, I thought that this film made a powerful point about evil: it precisely doesn't need to be explained. (This is what, incidentally, the remake of "Halloween" got so wrong, trying to find convenient, satisfying motivations etc.) The most terrifying aspect of evil is -as Dr. Loomis himself once said (I paraphrase here)- that it exists for no reason: it just is. Some people will want to hurt others.
The fact that no explanation is given (by "F") makes it all the more powerful: the characters under attack can't find a way of foiling the assault, being at a loss to comprehend what's going on.
The fact that the attackers' faces are not shown and they don't speak is part of this deliberate tactic.
If you can cast your mind back to Spielberg's first movie("Duel"), you will remember that the trucker's face is never visible! That's what made him all the more terrifying.

Also, the film answers one of your questions ("why the hell were people still in the school so late?").

Best, L.

agree, waste of time for any minute watching this crap.

I agree.

And the people who pretend they don't want to know why things happened. You do really, you are just pretending you don't cos you liked the film.

This wasn't just a story about a mad killer who decided to hack people for no reason and therefore 'is just evil'.

This was many hooded killers and all in a school. Why did they want to do it? and what happened to them? Who were they?

These things should be explained so people can say, 'i get it now' instead of being lazy and just finishing because the main character escaped....

silly ending and no reason for anything = crap film

It may have been that the guy getting the F was a complete 'Red Herring'. He may or may not have been behind the attack, or in could be just a case of a group acting out of pure spite.

Having their faces covered added ambiguity to the hoodies. Was one of them the guy who got the F? Were they even students? Perhaps they weren't even human beneath their hoods.
Keeping the faces of the "Monsters" hidden has long been a troupe of movies and television; it robs them of their humanity, for example- Darth Vader, Michael Myers in Halloween. Keeping their faces hidden also hides any clue to their motivation, were their faces sneering in glee, twisted in rage, calmly impassive or full of fear as they stalked their prey?
Humanity's greatest fear is that of the unknown.

Their movement's could have been attributed to an inference that they were accustomed to stealth, useful in such criminal activities as burglary and evading the police. Such skill could also be developed by parkour or skate-boarding. Their stealthy movements could also add credence to the theory that they are supernatural creatures.

The security guards were on the night shift, Kate had detention, Anderson had to supervise his daughter, the caretaker was working and the rest of the teachers were just finishing their work before leaving. Despite it being dark, it may have just been at the time of year when the evenings get dark early; hence the lack of concern on the part of the Head-mistress and the police.

As for the ending; To have everything resolved may have seemed too "Hollywood" to have everything neatly resolved and not have been in keeping with the rest of the film. Kate's relationship with her father, Anderson's paranoia and alcoholism and his personal relationships and the problem of teen crime in society cannot be sorted in 90 mins and is an allegory for the themes it addressed.

On a personal note, I'm in two minds about this film. On the one hand I felt this film to be suspenseful and engaging. On the other; I felt it to be the wet-dream of a nihilistic Daily Mail reader.
