Went to watch this at the pictures with jnr yesterday.
It's ok, watchable, but not brilliant. My 7yr old son was scared at first(it wasn't scary at all) and settled in after half way through, got the end with smiles as he understood it more and loved the last part of it.
You need a british humour to understand some of the jokes, gave me the odd laffs here and there, but nowt special.
Would I recommend it? Not really, not unless there's nothing else on, or if you have kids, which is who it's probably aimed at.
