It's a good film but is a little odd at times an,IMO,is meant for teenagers or a bit younger.
I guess it contains Norwegian humour that doesn't rub off on me.
That isn't to say it hasn't got some great bits,it has.
Obviously,the hammer training is good as are the scenes when it gets used properly in battle.
I particularly like the way it can be flung around the world !
And the brave girl trying to 'protect' her father with the intermittent help of a hapless hero.
The horn bringing into being the cloud bridge to Valhalla is pretty cool too.
So that's how it works !
So,once you've accepted the low brain drain plot,It's Ok I guess.
