This is a kind of a mixed review. First, I'll get to the stuff that I liked about "Impulse". The movie doesn't try to do too much right away, instead attempting to slowly build a sense of terror. The protagonists are less stupid than what you usually get in a movie like this, figuring that something is wrong fairly early on. The actions of the sick townspeople are believable and creepy. And some of the photography is really good, giving the viewer some striking images.
Now, the bad stuff. The movie is ultimately TOO slow for its own good. If things were speeded up a little bit, the movie would have had an acceptable pace. While some of the photography is good, much of the movie has a flat made-for-TV feel (not surprising, since this was made by the ABC television network.) The revelation of what's causing the mayhem is not done by detective work, but more feels like the screenwriters were getting near the end and felt they had to reveal it right there and then. The ending is also unsatisfying, leaving several big questions unanswered.
