ETA: Sorry, acidentally put in a spoiler........ Removing now but it might be too late........
I watched it with my 5 and 6 year old yesterday and I feel like I made a big mistake.
I don't wrap my kids in cotton wool or anything but even I felt this film was surprisingly violent. I mean, its owls right???? Yeah they kill their dinner, my kids watch and love nature films so natural violence they are used too but this film with the freaky bats, sharpened metal claws, special blades etc,was I felt, pretty horrific. I just can't help but think that if this weren't animated and it wasn't owls, the rating would have been higher.
It is a PG but its still not what I expected from a PG, i dunno, I know a lot of parents who went to the cinema when we were there were shocked as well, some walked out early, kids totally freaked and from what I have read of reviews its a similar situation.
I checked out the trailer and it didn't look too bad, I dunno, I am not usually weird about films but this just didn't sit right age wise for me and it seems a lot of other people feel the same.
