Saw it on Sunday -- the cinema was quite full...despite the guy behind the ticket counter trying to discourage people
"Can I have a ticket for Them please"
"You know it's a French film?"
"Yes"
"...with English subtitles?"
"Yes"
"...do you still want a ticket?"
Between Haute Tension (Switchblade Romance) and Ils (Them), French horror is really delivering!
I think the best thing about the film is that it's quite short, so it never really outstays its welcome -- just gets right into the horror (based on a true story) and doesn't let up.
The climax is quite disturbing, particularly in the context of the real life events!
