Disclaimer: Let me start by saying that I was neither drunk nor high when I watched this movie. I watched it stone cold sober, alone, in my living room.
Amazingly I just gave an Uwe Boll film 8 stars, I know, I can't believe it myself. If I were twelve years old and still read MAD Magazine I'd probably have given it ten stars.
There are plenty of "zany" pop culture riffing movies out there, (Meet the Spartans, Super Hero Movie, Date Movie, etc.) but the difference here is Postal works. I laughed throughout the entire movie, with the exception of about seven jokes which didn't make sense or just didn't work. But it doesn't matter that these seven jokes failed because the movie is an endless stream of jokes, sight gags, bikini clad cult members, machine gun battles, and bad taste in the vein of John Waters/Troma Films earliest efforts.
It's too bad Uwe Boll got himself involved in a petty internet pi**ing contest over this film. I think had he just been modest, kept his mouth shut, and let the film speak for itself it may have been a minor success. The old Hollywood saying about there being "no such thing as bad publicity" doesn't work for you when all you get is BAD PUBLICITY.
That said, the only real problems with the film are the low budget production values and a few of the minor performances, but even those problems just add to the humor of this film.
The plot actually made sense.
The actors played it straight without being too zany too often.
And the jokes, although in bad taste and definitely not for everybody, were never so mean spirited that I was turned off by them.
I think Uwe Boll knew what he was doing with this picture. The satire and parodies worked well, and there were even a few jokes that made me want to cheer. I know, crazy huh?
