Recently my daughters have been big on wanting to watch the Pirates films. For the most part rewatching them I haven't seen anything to egregious. Then we watched On Stranger Tides. Now I haven't seen this movie since I half watched it with my old college gf when it came out. Even then I remember feeling the movie was biased against Christianity. Specifically the feckless missionary who doesn't have any balls.
I digress. Even back then and now seeing it again I think the twist with the Spanish Catholics is great. Maybe I am biased since I'm Catholic. But the way they just destroy all the pagan shit while all the British and pirates are confused is great. "Only God can grant eternal life, not this pagan water. Men destroy this profane temple". I remember reading reviews back then considering the Spanish villains. Now I see them as heroes.
It's a shit movie, but unintentionally based.
For those interested
The movie version of Starship Troopers is a pretty good example. I don't know what Heinlen's (author) opinion on the government and military system of the Federation is, but Verhoven (director) was openly disdainful of the book, admitted he didn't even finish reading it, and said he made the movie as an anti-fascist parody. He did such a bad job that he made a pretty decent movie that made the Federation look awesome.
The book is extremely based. Really good philosophy.
