I started watching Children of the Night but lost interest about 20 minutes in. It was slow and a little boring, and I just was not feeling it. Sometimes movies find their footing and pull you in, but a lot of times they do not. Lately my approach has been to give something a reasonable window, and if it does not grab me, I move on. Children of the Night fell into that category. Maybe it gets better further in, but I did not stick around to find out.
