Didn't like this movie because the aliens became a huge joke by the end.

I could get over the fact that the protagonists were hoodlums. What made me shake my head was that the aliens got progressively stupider and became a joke by the end of the movie.

So when we first see the aliens they kill the two police officers. They jump from out of the shadows and instantly stealth kill them. You think, okay these are highly evolved creatures that are bred to kill. Then it all goes downhill from there. You have the aliens mindlessly chasing the kids in the open while roaring, the kids (KIDS) are able to survive bites from their jaws, which look dangerous but apparently have less biting power than a dog. They go from sneaking up on their prey to bursting into windows and doors, making the most noise as they possibly can. They get killed by two teenage girls with a broken lamp and an ice skate. Two 1st graders kill one by shooting it with a super soaker filled with gas, and it just started chasing its tail saying, "gee please kill me." Weakest alien invasion ever.
