Ah, The Tower from Guillaume Nicloux. To be honest, I didn’t see much point to this. It is a rather bleak, dark, and slow film about what happens when an apartment building becomes completely cut off from the outside world because it is enveloped in a blackness that just seems to disintegrate anything that enters it.
People are in a panic, at first. As times goes on through, they just band into opposing groups of terrible people (of course). And they are rather pointless power struggles and violence, and dogs become a hot commodity, and, as the years go on, the thug element becomes just more and brutal, and just nothing good (or particularly interesting) happens at all.
