Whether one believes the restrictions are too tight or too lenient, it is undeniable that there are certain limits to what one can show on broadcast and basic cable television. Thus, it is not a surprise when television series that have a clearly more "adult" bent to them opt, when making a movie, to use copious amounts of profanity that would never make it into a traditional broadcast.
As an example, think South Park: Bigger, Longer, and Uncut. The newly released Tripping The Rift: The Movie does not take that route. It does have some profanity, but not as much as one would expect from the normally quite lewd series.
The film, as the series before it, takes place well in the future and follows the exploits of Chode (a purple alien blob) and his crew of misfits: Six (a sex slave robot, played this time around by Jenny McCarthy, but in the past by others, including Carmen Electra), Whip (a teenage slacker lizard), T'nuk (a cow-like, bug-eyed alien who is the pilot), Gus (a gay robot), and Bob (the ship itself). The basic plot, such as it is, has the crew trying to escape a robo-clown sent back from the future to prevent Chode from impregnating the bad guy's (Darph Bobo) daughter, Babette.
Just as the series did, the movie spends much of its time spoofing other movies, shows, and pop culture references. Thus, the robo-clown appears Terminator-style (naked and in a sphere), and speaks with a bad Arnold Schwarzenegger accent. Other moments in the film, harkens back to the Universal monster movies of the 1930s, the Indiana Jones films, Desperate Housewives, and Alien vs. Predator. Plus, as it's a space odyssey, there are Star Trek and Star Wars references thrown in as well (not to mention some more pornographic jokes).
The basic concept of the film seems to be to throw up as many jokes and references as possible over the course of the 75 minute run-time in hopes that a few find their mark. Happily for fans of the series, enough of them do. It's unquestionably not as smart or witty as some of the series' episodes that came before this, but there's enough there that pop-culture junkies will be amused.
