Stephen King's The Mist

In watching this movie adaptation of a Stephen King Novella I couldn't help but compare it to The Happening. In that movie M Night Shyamalan, armed with some bizarre casting and some of the worst movie dialogue ever, attempted to convince that watching people run away from wind is a gripping cinematic experience. Was director Frank Darabont now out to kid us that a bit of mist could be terrifying?
Luckily Darabont filled his mist with all sort of CGI nasties and while they look a bit shiny and silly at times the movie at least delivers both shocks and gore. Not only that but the central characters actually give the viewer something to care about, which is more than can be said for Mark Warlberg's science teacher and his girlfriend agonising over dessert with another man while people continue to die all around.
It's not a brilliant film and it works best when it concentrates on the thrills and avoids vague nods towards science fiction or social commentary. The whole thing ends with a twist that any intelligent person should spot a mile off. I never saw it coming.
