Cloverfield (2008)

Although the movie's gimmick may be a bit much for some viewers, I found it extremely effective. It was a lot scarier than I expected it to be. It felt very real - both on the part of the everyday people caught in it, and the soldiers trying to find a solution. The creature itself is actually very scary, and the smaller creatures are completely terrifying. I felt the short length of the film also worked for it - it was able to pack more consistently scary moments into a smaller amount of time without going overboard. Overall, a very solid horror flick. 4 stars.
