Went into it thinking it might be disappointing and overly-American.
Not so. I definitely enjoyed it on the whole. Nice story and some good characters!
Had a pinch of that magic reminiscent of Lord of the Rings, as well as a generous dollop of Narnia for good measure.
Really stunning special effects and opulent sets, with a fantastic part played by both Michelle Pfeiffer and Robert De Niro. Also a pleasant surprise to see unexpected cameos from Adam Buxton and Mark Williams! David Walliams also features, but I knew about him. Ricky Gervais... good part, quite funny but as ever, it's the same character in everything he's in.
As said above though, it doesn't really pick up until about half way through. Also, there's a lot of chopping and changing between scenes in the first half which is slightly annoying.
I'd give it a 7/10.
Enjoyable film. You'll be glad you saw it... but make sure you pay attention during the slow first half.
