I don't think this movie had any right to being as good as it was. The casting of Tom and Rob is phenomenal. Tom does an amazing Ned Flanders and the introduction of our main protagonist makes you as an audience member understand that she is a capable and resourceful person so that it doesn't feel unearned when that comes up later in the movie. The driving antagonist is shallow and dumb, which works perfectly, and the real threat is obvious early on, but still gets good reveals and ramping tension. The characters make seemingly logical decisions which helps build tension, and the movie is well acted and shot, way better than it had any reason to. Overall, I really did enjoy this movie and if you aren't arachnophobic, this probably is a good flick for you too.
