How realistic are these "Home Alone" movies?

Hardly. I think the kids like it so much because they see the adventures,which they want to do ,but can't ,in this movie. Every child want to be strong (enough for win against 2 gangsters), so smart to make such traps ,and so brave to do all these things without fear. But all these qualities together, in my opinion, are impossible for one kid to has.

I like that movie a lot, and my son too, he always tells me how he is going to kill the gansters if they como to our house, lol, but of course that is not true, there's not way that a little child can go against two gansters. Have a nice day.
