Not PG enough

I wish I would've watched this on vidangel. I'm learning that a PG rating is not enough. My household's Christian values go beyond PG. Personally I found the jokes to be comical, but not appropriate for 7 year olds. The scenes that I didn't like were 1. The human teaching the other alien how to get an alien girl which ended in them almost kissing. 2. The human drops his towel, and he aliens comment on his "antenna." 3. Very first scene in the car. I fast forwarded it.

Is It Any Good?

Our review:
Parents say (22 ):
Kids say (53 ):

Even if you take Pixar's incredibly sophisticated, high-grossing movies out of the running as a comparison, PLANET 51 is uninspired and forgettable. The movie's animation (particularly the landscape backgrounds) is flat, the dialogue is overly cluttered with pop culture references (to everything from The Right Stuff and E.T. to The Terminator and the Macarena). Allusions and double entendres work when they're seamlessly woven into a family-friendly script (as in the Shrek movies), but the lame penis and anal probing jokes are just off-putting in Planet 51.

Young kids may be drawn to the alien characters, especially comic book-obsessed Skiff and the dog-like creature that has toxic pee and a penchant for terrorizing the local mail carrier. And adults may get a laugh or two out of Neera's suitor Glar (Alan Marriott), a VW-van-driving, guitar-playing hippie who protests the planet's violent reaction to Chuck. But Johnson, who has proven he's a surprisingly talented family movie star, isn't given much to work with as the cocky astronaut, and Lem and Neera's "romance" is only slightly amusing when Lem goes to Chuck for dating advice. Ultimately, if you're hankering for '50s nostalgia, check out Back to the Future -- and for animated alien comedies, stick with Monsters vs. Aliens.
