My easy child (she's 10) can't take fight scenes or things of the like, so she didn't watch it. I know at that age, my difficult child would have loved watching it.
I did watch this movie with my S/O and found it quite good actually. I think if he's adventurous, he'll probably enjoy it alot.
If that is up his alley, we bought Tim Burton's "9" to watch last night and again, easy child wasn't watching (She was at her dads house for the night anyhow) but the 3 of us were glued to the t.v.
It is brilliantly creative and I can say I highly recommend it.
