Scary Movie 4 is full of more recent movie spoofs than its predecessors. However, at that time period, the movie variety was limited so the spoof movie that wouldn't be good at spoofing good movies, is stuck spoofing War of the Worlds and the like.

Religulous blends humor with documentary in a way that it is still a legitimate documentary.

Its this movie. And that is a true story. And this was a terrible movie.
