It has been a very long time when any movie gave me the chills, especially a horror movie. Well, I got one in the middle of the movie "Insidious". It is a throwback to the classic horror movies even with the old school music. (My friend who has not seen many old horror movies thought it was very odd.) I won't tell you exactly where I got the jitters but it definitely happened.
The movie as a whole was pretty darn good too. No plot holes, no items outside the realm of the movie logic, no impossibly stupid or smart people. I did guess the ending but my friend did not. Also no crazy amount of gore for no reason. What really kills a movie (other than the commercials giving away the ending, which this did not luckily) is seeing more blood come out of one person than they could possibly have in their entire body. This never happens and I am very glad.
So if you like to be scared, or are one of those people who like to spend half of their time in the theatre watching a movie between their fingers, give this one a try. Watching with a packed house made it even more fun. I swear some girls were just screaming because so many others were freaking out next to them. Don't worry, I'll be there to protect them :>
