If the only thing City of Ember does is show that Belfast can play host to high concept movies, then it was worthwhile, but no doubt, it was aiming for more than that. Perhaps to stand next to such fare as Harry Potter, or a Pixar flick.
Unfortunately, it falls short, but only just. This is without doubt, an exciting romp about two coming-of-age children who break out of the mold forced on them by the dying Ember, and in doing so, change everything. The acting is solid, the set design and music excellent. The concept, the builders of Ember leaving behind secret instructions to get back to the world, is genuinely engaging.
Unfortunately, they don't get to these instructions fast enough, and a lot of time is spent wandering around the, albeit, beautiful city. Often times there is a lack of a perceived threat. Despite being replete with a nefarious mayor and a mutated mole (like the massive moths, never explained), the story uses neither of these things enough, leaving some scenes to be propelled solely by the heroes following the by-the-numbers instructions left to them. Worst of all, the ending feels like a poor man's Goonies.
In the director's corner, he is guilty of some slow scenes, but what is almost unforgivable is the flat looks of the actors during intense CGI action. Somebody wasn't thinking ahead.
Nonetheless, a charming film that I hope made enough money to spawn treatment of the books sequels.
