Do not be fooled by the people on here who have given 9 or 10 stars. If you check their profile you will see that this is the only film that they have ever reviewed. Sadly this is a trend which has become all too prevalent on IMDb in recent years. I really wish the site would sort it out.
The film itself is a well-worn and tired theme and the funny lines are not funny. My advice is to avoid this film at all costs unless you feel particularly like being angry with yourself for having wasted an hour and a half of your life. To be honest, I am not sure what the intended audience for this film is. I am not opposed to films about social, religious or national groups if they are done well. Mel Brooks was a master at this in his heyday. Borat was a belly laugh a minute. However this film fails on so many levels. Avoid at your peril.
