I just watched this tonight (already had it and never thought to post it here). That's because you should know that this is mosty a boy (and dog) movie. Let's say 85% the main boy and his friend who's a boy and the dog (who is played by a girl dog but that doesn't count

), 5% his friend who is a girl (the last picture above) and 10% his two sisters.
It's a good family movie, don't get me wrong, I am glad I watched it. And the girls are cute, just not the focus.
This is the third in the series, with prequels released in 1995 and 1999, with some of the same actors (except the kids who obviously would have grown more than the year or so screen time between the movies). I can't find either of the prequels on eMule at this point. I have the first and will watch it when I get a chance, and will release it if it's good.
