It takes nearly three quarters of an hour before they actually reach the centre of the earth. Just so you know. That's a long time of no fantastic world in the film.
Also, there is no sense of immersion - you can really feel that the actors spent most of their time green-screening and the poorly aged CGI doesn't help.
I WANT to like this film, given that I'm crazy about guinea pigs, but that very fact made me pretty mad with all the depictions of poor husbandry and generally bad animal care in this film. Yes, I know it isn't real, but I also know that kids copy what they see on screen and I pity the animals that were bought as a result of this film.
