So, when his Grammy tells him that a mysterious being known as the Once-ler who lives outside the walled city has the key to the trees, Ted sets off to break out of Thneedville and discover what exactly happened.
But Ted's quest isn't going unmonitored - for hot on his heels and watching his every move, is greedy corporate baddie Mr O'Hare who owns a bottled oxygen company and who fears that if Ted gets his way, his empire will come crashing down.
However, when Ted finds the Once-ler, he discovers the guilty secret that he holds and how his quest to make a Thneed from the trees left them with a wasteland - despite the intervention of the spirit of the forests, the moustachioed Lorax (Danny De Vito).
Can Ted make a difference to what's gone on?
The songs which permeate the brightly orange coloured film are clearly cleverly written to support the whole "Let's save the environment" stance of the piece. And it gets a little tiresome quite quickly. There's something insidious about the lyrics which get stuck in your head - the final song, a gospel style ode to the trees, is called "Let It grow" and for days, it's been lodged inside my brain like a seed growing away.
There's nothing wrong with that stance and fair play to the creators for so heavily pushing it but I just feel like the message was sledge hammered home over any level of subtlety.
Which is a real shame - because the animation, complete with its requisite looniness which you'd come to expect from the creators of Despicable Me, suits the piece perfectly. There's little of Seuss' rhyming within the film itself though and while the younger end of the audience won't care or notice, maybe fans will feel a little cheated. The film skews toward a younger demographic and while that's not a bad thing given the orange brightness of the whole piece (even the Lorax looks like an over spray-tanned Mark Sainsbury from Close Up), there's a small part of the film where the energy levels take a hit and it sags a little.
Overall, The Lorax isn't bad - it's just that without the much needed easing off of the "Save the Trees, Save the Planet" message, the whole thing's a little heavy handed and leaves a sour taste in the mouth rather than the bouncy joy a Dr Seuss book should be.
