I bought this on laser disc years ago, and it has always been a favorite of mine. Many friends who watched it with me agreed. Anyone with just one romantic bone in their body will enjoy the girl boy interplay, especially if you like science fiction (as I do). The unusual pet they bring with them adds greatly to the story. The two 'alien' girls are cute, the effects are quite good and Keenan Wynn, in his 174th movie, his last role, plays a very likeable and understanding, openminded grandfather. I found it to be great fun and when I realized today that someone really tried to badmouth it badly, thought I had to give that a counter. It is not a cerebral piece, but most movies aren't. I am happy that I found it because I have never seen any advertising for it, which I found somewhat surprising. Also, it is something that kids can enjoy with its wholesomeness.
