Reading some of the reviews, I thought Rango might not be suitable for my three year old daughter, and considering it was a PG I had a watch of it first to see what I thought.
The film begins in a very similar way to the excellent Aardman/Dreamworks Flushed Away, a pampered but lonely pet is thrown into the wild world and forced to fend for himself.
It then morphs into the classic western plot, stranger in town, corrupt mayor, gunslingers etc, all played out by a cast of beautifully animated ugly wild creatures.
Yes, it is weird, the animals are not standardised Disney/Pixar/Dreamworks cuties - they are rough and ready, battered looking wild creatures.
Yes, some of the references - Fear and Loathing in Las Vegas, Clint Eastwood westerns, assorted Tarantino-esque moments - will be lost on little ones, but then the best animated films appeal to all age groups.
After watching I decided my daughter would get along OK with Rango, and it has quickly become a favourite, being requested most days!
I would say that if your kids can handle the weirder side of animation - my daughters favourites include Coraline, Wes Anderson's Fantastic Mr Fox, the Nightmare Before Christmas and the Studio Ghibli movies - they will love this film. If they prefer their animation a bit more cute and cuddly, perhaps steer clear or buy it for the grown ups to enjoy!
