This was a great scary movie, but I didn't feel uplifted after it (I don't know that there are any inspiring scary movies). There were some heroic people throughout it saving other people's lives from the monster ravaging Manhattan. It did not feel evil, a light humor was trickled throughout it to keep you interested in the movie without being overwhelmed with the constant destruction/bloodshed.
Part of the reason it wasn't evil, in my opinion, was that the monster(s) was(were) very unrealistic. A lot of times when one can realistically imagine the "bad" from the movie in their own real world (e.g., as possibly being pursued or having loved ones in danger), the "bad" can be more lasting in the watcher's mind causing nightmares or other fearful images. Evil can also be advocating or displaying sin in a way that glorifies the sin and does nothing to denounce it or display the consequences of such actions.
