It isn't terrible, but it's still illogical.

Rating: 4/10 (8 April 2012)

I am going to say I don't hate this movie but to me it is rather bad and the plot has some huge holes in it that some people need to consider before praising this movie.
The whole movie deals with aliens that have touched down and are terrorizing Mel Gibson and his family, by the way Mel Gibson in this movie is a lapsed priest after his wife died in a car accident.
The idea sounds interesting, but there are huge plot holes in this movie:
1. Water is lethal to the aliens which will kill them by contact, yet the aliens came to a planet covered by 75 percent of water, precipitation is constant and dew settles on corn at night, so the aliens running through the field should have been killed instantly.
2. When the aliens finally break into the home the family fleas into the basement, and the aliens that are capable of inter-space travel and cloaking their space ships cannot get through a wooden door.
3. After the family holds them off, the next day Joaquin Phoenix opens the door and goes upstairs without taking the ax or any other weapon with him, sounds extremely ignorant to me.
This whole scenario is ridiculous but on a positive note the movie does have some pretty good scares and an effective soundtrack, and the acting wasn't bad either.
But those things are not enough to save this film for me, but those reading this if you can stand giant plot holes then by all means see this film, but all others it's better to avoid it, watch M Night's previous two films instead.
