Saw this for the first time where it was decidedly presented/screened in Black & White as Frank Darabont originally intended.
I'm perplexed to revisit it in color. The B&W really brought out the Romero influences, the odes to classic horror, neat shot composition, unique lighting choices, depth of field, nice integration between (relatively dated) CGI and practical effects, the list goes on forever.
Mostly everything is expertly done in this King adaptation that feels reasonably overlong but consistently entertaining. Any times it goes overboard can be drawn to how the novella was written, so as an adaptation, I'm sure it succeeds.
I love horror that isn't afraid to flaunt its monsters, as the creature effects and designs are superb and fun to watch. We are able to watch them parade the screen for sustained periods of time and it sure adds to the frights.
P.S. everything you've heard about the ending is true. Twisted stuff here.
