In the modern genre of computer animated kids films, this ranks among the very best. Unlike so many kids films, adults will enjoy every minute of this one - with or without the kids.
It's a simple story, of course - my 3 year old had no problems following the plot. But there are endless background funnies and asides for the grown ups that make this film a gem. Like Shrek, the heroes of this film are about as imperfect as they come. Much of the humour comes from the interactions of the 3 main characters, none of whom particularly want each other's company.
Lisping Sid (lishping shid) is hilarious throughout, and the squirrel who turns up between scenes will split your sides.
With none of the gushing sentimentality that Disney relentlessly pump out, this film is way out in front of other recent mediocrity, such as Dinosaur or - God help us - Jimmy Neutron. In my book, it even beats Monsters Inc for all round family entertainment.
This is the best kids film since Shrek and is a lot more entertaining than many recent adult titles.
Buy it - however old you are!
