This is often called the worst movie ever made. I really don't think so. Of course it is not a masterpiece, but hey, it is a parody and never tries to be something great. There are several movies that pretend to be epic and come out unintentionally funny or boring.
"Date Movie" mocks romantic comedy and is - as it is a spoof - cliched and over-the-top.
There are several scenes in this movie i found very funny, such as the "Kill Bill"-parody or the Milkshake dance sequence. Some jokes seem to be pre-funny, but it is not what i call the worst movie ever.
There is an off-screen sex scene that can be heard, but not seen.
Lots of sexual innuendo throughout.
A decaying corpse is seen, a man shoots several women, a man nails his own head (no blood and comic) and a girl and a man beat up a homeless guy.
A man's name is "Fockyerdoder", but it is pronounced "F*** your daughter".
The movie should be okay for teenagers 12 and up.
