I dont think it is going to be "bad" for your kids being that there is no foul language, drugs, sex etc... I personally thought the movie was hilarious, but probably because I'm an 80s kid. I would let them watch it, but they will probably get bored and distracted. The most entertaining parts for me were the things I saw and heard that I remember being a part of my childhood. So IMO the reason so many people gont get it or dont like it is that it just doesnt have that nostalgic value it does for me.
