Actually the trailer tells you the whole movie.
And it is really about some zombie kangaroo who kills a lot of people in the Australian Outback.
It sounds like a hilarious, funny horror comedy you'd enjoy watching and have a good laugh at - but noooo.
The biggest flaw of that kangaroo zombie flick is that it totally wastes that opportunity and tries to be an earnest shocker movie.
But that does not work, because while the movie takes itself way too seriously and tries to scare you, it fails miserably because once "Rippy" the zombie kangaroo enters the scene you can not stop laughing at all. :)
And that's not only because the whole idea is so silly but because they used some very cheap and obvious CGI for "Rippy".
"Look - it's Rippy the zombie kangaroo out of my old computer I made with the help of the book "Cheap CGI zombie kangaroo for dummies" :)
The movie never gets any good it isn't even so bad it is almost good.
Unfortunately it isn't really worth watching.
I almost felt sad for poor ol' Rippy, who desperately tries to scare you, but you always end up laughing about it.
And I was really looking forward to watching a funny, braindead movie with the typical down under humor - but nooo - instead I got "Rippy" the serious serial killer movie about a zombie kangaroo.
Facepalm!
