We recently took my two daughters ( ages 5 and 7 ) to the movie theater for the first time to see how they would react to it versus watching the movie on DVD. We saw Aliens in the Attic as they picked it out of a few films suitable for children.
They really enjoyed the film and in fact so did my husband and I. the movie was fast=paced enough that it was not boring and it was made in such a way that adults and children found it entertaining. It did have some actors that my daughters knew from the Disney Channel but they seemed to like all the characters even the Aliens.
I recommend this film for children over 4 or 5 years old as it is very well produced and kept us adults interested as well as the children
