While there is funny content, the story jumps from step to step far too quickly, as is often the case too many insider adult jokes and the quick devolution into killer aliens was quite scary for the younger kids.
Also, as others noted, using things like "wanna be my lover" and other content seems more of a tool for a "sure thing laugh" rather than creative content that stands by itself. Again as others said: why unspoken the missing parent? Really? Needed?
That all being said, I was laughing myself.
I think keeping it at least to a mature 6 year old and up is warranted, if only for the killer aliens.
